The DarkSphere + "What’s In My Bag" ::

darksphere.jpg

Many of you have asked about my DarkSphere that I used in the GPP group shot photo. It is pictured above attached to a Nikon SB-25. It is painted silver on the inside and black on the outside. I do not suggest painting it silver on the inside because it took about 18 months for the silver paint to dry on the inside. Paint it white instead or don’t paint it at all. This is for the soft squishy model of the Lightsphere. That is a Speedotron 10 degree grid bunjeed to the flash.

Why did I do this? I like for grids to be placed a little bit off of the face of the flash head. I find that it gives a cleaner circle of light and it is much easier to bunjee to a small hotshoe flash. So I took a Lightsphere that someone gave me and painted it black to act as a sort of parabolic reflector like you find on 120j’s and Q-flashes. It works exactly as I want it to work! The problem with painting one of these is that you can no longer use it as a food storage container or a cocktail glass. Oh well.

While we are nerding out and talking about gear, I thought I would do one of those “what’s in your bag” blog posts that were popular a few years ago.

For my bag I use the ThinkTank Airport Security roller bag. This is THE best camera bag I have ever owned and it has more miles on it than I can count and every stitch is still in place. I love that I can lock the main compartments as well as lock the tethered cable to something so someone can’t simply roll off with it. They have to show up with bolt cutters to take off with this thing.

I’m off to shoot a big Indian wedding in the morning and here is how it is packed.

In addition to my Speedo grids, I also keep two Honl Photo grids and a snoot in my bag. They are nice to just have something to slap on to a flash quickly. Here is the front flap compartments.

mybag02.jpg

Yes, I’m packing both systems tomorrow. @Steve_Gray asked on twitter, “Isn’t that like packing matter and anti-matter?” Hahaha! So true. Notice I had to separate them or else they would be fighting to the death!

Which one do I love more? Can’t say. Can’t say at all. I will tell you this though… when it comes time to shoot the reception tomorrow night I bet you the 5d goes back in the bag because the auto focus is useless in low light. You’d think they could do something about that. The D3 can focus in just about any dark environment I find myself in. The 5d requires you to be standing on the surface of the sun to have enough light to focus. Ok, maybe not right on the surface but pretty close. The AF system on the Canon can not even be compared to the Nikon. In this area Canon sucks and Nikon rocks. The rest seems to be up for debate.

I’ve been shooting with them side by side for the past few weeks and I’m confident I can keep them straight now as far as the vast difference in controls on each one. If you have any questions about gear and such hit me up in the comment section.

GPP Group Shot = Pressure That Can Make Diamonds

gpp_blog_final.jpg

On the next to the last day of Gulf Photo Plus I was informed by GPP organizer, Mohamed Somji, that I had the “privilege” of shooting the group shot of all the GPP staff and photographers. I would be given 15 minutes to set up and execute the shot with 25 to 40 people.I have done countless group shots in my young career but never one that had folks like Joe McNally, Drew Gardner, David Hobby, Chase Jarvis, David Nightingale, and on and on and on. No pressure.

Last year David Hobby shot the group photo. He did it available light and had the photo posted on the web in 30 minutes. He was smart. David kept it simple. I however had could not leave “well enough” alone. I wanted to make a picture that was a tribute to some of the photographers in the photo and I wanted to keep with the OneLight theme so I decided I would get everyone in the auditorium and light them individually with one light and then comp them together in post. I have “painted with strobes” a few times in my life but never on this scale. It isn’t the most technically brilliant photograph I’ve ever made in my life but I had fun doing it. Everyone in the room had fun bustin’ my chops for taking this on. Hobby had a GRAND time playing with his wizard in his pocket while I was setting this up too. :)

How I did it = Pretty simple

• I set my camera up on a tripod so that each shot would align in the final image to be created.

• I had my studio manager, Erik, walk around the room with a Nikon SB-25 mounted on a tripod. On the SB I placed a Lightsphere that I have painted black. I call it my Darksphere. I then bunjee’d a 20º grid on the front of that. I like to have my grids placed off of the flash tube to get a cleaner circle of light.

• I exposed somewhere around 5.6 at 250th of a second to kill the ambient light in the room. I just needed the light on each person. There are 29 people in the final shot and I used 28 frames to capture them all. Chase and his wife, Kate, were lit together for one shot.

• I tried a quick multiple exposure shot on the back of the D3 to see if my idea was going to work. In this you can see Erik holding the light on the stick.

gpp_test_011.jpg

This is what each individual shot looked like…

gpp_mohamed.jpg

This is what the group shot looks like without the auditorium showing through…

gpp_black.jpg

Here is the auditorium. I would use this image to mask parts of the ambient back into the group shot.

gpp_room_shot.jpg

Once the people were together I could then bring in the image above and again, using layer masking, I painted in just enough of the ambient light to mix in with the lit shots. The final shot was 34 layers tall. 28 layers of people and 6 layers of ambient light and details like the the strobe painting on the back wall panels. Here it is again…

gpp_blog_final.jpg

So…To Joe McNally – I know you eat 30 Speedlights for breakfast every morning so excuse me while I meagerly try to pull it off with one.

To David Hobby – My light rig for this shot not only has a bunjee cord on it, but it has a LightSphere that I spray painted black to keep with the DIY / Modify philosophy you preach so well.

To David Nightingale – 30+ exposures to make one final image! How do you do it so well? You can see how much of a hack I am.

To Drew Gardner – If only I had a water buffalo and 300 gallons of strawberry jam then you too would have a tribute here. :) Maybe next year I’ll shoot it on a Phase One. Oh wait! I don’t have to shoot it next year! Some other light monkey will have to do it!

To Chase Jarvis – You talk about pushing yourself. Well… I pushed myself on this one!

I could have done this or that or the other to make this shot better but I had no time to really think it through. It was a good exercise for me though. I’m glad I did it this way.

I have one more Dubai post to make this week and then we are back to regularly scheduled blogramming.

I Feel Like I’m In A Tool Video :: Julia with the 5d Mk II

julia_01a.jpg

The image above states the exact feeling one has when shooting at this old prison in East Atlanta.

Here are some more images I shot this week of Julia. She needed one or two new pieces for her portfolio and I needed to run the CaNikon 5z Marc Too (as I call it) through the paces. Overall I’m really happy with this camera. For this shoot I used the 24-70/2.8L and the 90 2.8 Tilt Shift. I have to be very, very, very careful with the T/S lens because if I am not very, very, very careful I will use it WAY too much. The reason I don’t own a fisheye lens is because I would use it all the time. I fear I may do that with the T/S. It’s like instant creativity! :) My initial thoughts on the 5d after the images.

julia_08.jpg half_spacer.jpg

julia_09.jpg half_spacer.jpg In addition to the stills, I shot video as well. I don’t have the time right now to get the editing done on that but I hope to cut a short clip together soon.

Things I love about the 5d vs. the D3 I normally Shoot :: • Color and Contrast straight out of the camera. • A remarkable skin tone quality when shooting natural light. • HD video

Things I don’t like about the 5d vs. the D3 :: • The AF system sucks in low light situations. Every Nikon I have ever owned from the D100 to the D3 can lock focus faster and more accurately than the 5d does in low light levels. • Nikon still pwns Canon at ISO 3200 and up. • It’s slow as Christmas compared to the shooting speed and buffer of the D3. • The ergonomics. The 5d feels like a brick in my hands even with the grip. The D3 feels like a glove.

And yes, I’m aware that I’m comparing a mid level Canon to the top of the food chain Nikon.

The number one reason I have this 5d is for the video as I’ve stated before, but I also love that there is a specific quality to the images this camera produces that I find other cameras do not have. Back in the days of film you would choose one film over another based on the characteristics of that film and the type of color, contrast, and quality that you desired for the shoot you were doing. Since we can’t simply change sensors in our camera bodies like we could change film, this particular time in digital photography requires us to change the entire body. In the studio the cameras are nearly identical.

It is in the available light photography that I find the 5d to perform remarkably different. Skin tones have a smoother quality to them akin to something with warm butter all over it. The Nikon can be a little too cool and too sharp for my liking. You can spend time in post trying to replicate one look or the other but when you study enough images online and you KNOW an image was shot with a 5d without looking at META data then you know the camera has something special about it.

The same could be said for my D70. I could do things with that camera in post production that I have yet to fully replicate with any other digital camera I have owned. The camera body is now the film base and you choose the one you want for the look you desire. That’s why the 5d is going to have a permanent spot in my bag in addition to the video capabilities.

First things first. If you want a copy of Meghan’s song, “Window”, from the Transform video. Just click this link. She wants to remind everyone that this was just a quick recording during a practice session but it currently is the ONLY recording of this song. So, it isn’t a perfect recording but you know what? This whole post is about doing it lo-fi! If that link stops working, we’ve gone beyond our bandwidth and I’ll find another place to host it. If you want to find more of her music, you can find her on iTunes under the fantastic name of Meghan Coffee.That was her name before I ran off with her to the judge! :)

RadioPopper Is Changing The Game ::

February 14, 2009 | News • Gear & Gadgets • Resources

OMGosh… Kevin has changed the game.  He may very well be going down in the history books for this.

The image above was shot with the new RadioPopper.  The amazing feat is this image was shot at 1/8000 of a second with an Alien Bee.  NOT TTL high speed sync. Unbelievable.  I wish I was going to WPPI to shake his hand.  This changes the game.  If that isn’t enough, the new RadioPoppers can adjust your Alien Bee and White Lightning gear… wirelessly.  

If you don’t know WHY this changes the game, you need to get in the game.  :)  

Interestingly enough, Pocket Wizard is about to unveil a new model.  If it does not give us high speed sync with ANY strobe, they really need to get back to the drawing table.

Putting my order in now.

Cheers,

I found these images yesterday as I was helping Marc get set up for a bridal show he is doing today.

I’m the kind of photographer who would LIKE to be the kind of photographer that always has a camera around his neck. My darling wife hooked me up with a Canon G10 for Christmas last year and I’m doing my best to take it with me where ever I go. I love this camera.  

Not counting a cell phone, do you have a small camera that you take along with you on a regular basis?

White Seamless Tutorial :: Part 4 :: Simple Changes In Post Production.

ws_part4_01.jpg

If you are just joining us, this is part four in a multi part tutorial about the many uses of white seamless as a background material. You can catch up by reading part 1, part 2, part 2b, and part 3.

For part four we are going to look at making simple changes to our photos in post production. We are going to change the composition of our photos shot on pure white or pure black. We will also look at a way to add some color back into the background on the images shot on pure white.

The first thing we are going to do is change our composition. When I’m shooting on a pure white or pure black background, I shoot 95% of those images vertically. I fill the frame with my subject as much as I can. I want to maximize the image area they take on the sensor of my camera so that I have more options for enlarging the photo later if I want. If I want a lot of negative space in the final photo, I’ll add that in Photoshop later because it is easy to create white or black space and still have a full frame of the subject. Imagine the area of your camera’s sensor for a moment with the photo above on it as it is captured…

ws_part4_06.jpg

That is a lot of dead space thrown away on your chip. You can maximize the captured resolution of your subject by filling the frame.

ws_part4_07.jpg

There are two simple ways of expanding your photo to change the composition. You can change the canvas size or you can use the crop tool. I prefer the crop tool because it lets me visualize the new composition I’m trying to create. For the example below I want to deliver the vertical full frame shot to the client and I want to deliver a horizontal shot as well. I’m going to keep them set to the same dimensions by locking in my aspect ratio then flipping the width and height numbers. See the photo below.

ws_part4_02.jpg

The crop tool options can be blank if you want so you can free form a crop. Here are the step to expanding it.

1. Make sure the photo is a locked “background” layer.

2. Set the BG color swatch to pure white.

3. Select the crop tool and pull it out over the image. It will not pull out beyond the edges of the photo. Once you hit an edge of the photo LET GO of the mouse button. Some bounding box tick marks will show up on your crop rectangle.

4. Grab one of those bounding box tick marks and begin to pull the crop out past your original image.

5. Once you have the composition you want, hit enter or return to apply the crop. Since your BG swatch is set to white it will become the color of whatever is beyond your original image after it is cropped. Its magic and stuff!

ws_part4_03.jpg

ws_part4_04.jpg

ws_part4_05.jpg

From looking at the next image, you would think I have a massive studio space.

ws_part4_08.jpg

This is how it was done.

ws_part4_09.jpg

Again, the original image was shot vertically to get the most bang for the buck out of my sensor…

ws_part4_10.jpg

We can do the same thing with images shot on a PURE black background.

ws_part4_11.jpg

Going through the same steps as above, I have now just changed the BG color swatch to black instead of white. I have also moved the light source around a bit.

ws_part4_12.jpg

ws_part4_13.jpg

I made a selection around the light then used the move tool to drag it around. With the BG swatch still set to black, it doesn’t make a “hole” in the photo when you move it.

ws_part4_14.jpg

Here again is the final frame after about 20 seconds of work in Photoshop.

ws_part4_11.jpg

That’s the simple simple stuff. Now we’ll add just one more layer to the pure white image to change it up a bit more… I sit with my clients and walk them through a series of changes. I let them know they are getting an image shot vertically but with some simple changes it can go to a larger vertical image for a concert poster or it can go to a horizontal image for a promo card or CD artwork. Here is another thing I show my clients that can change the overall look of the original image. Let’s make a square crop like we are doing CD artwork or something. Here is the original image as shot in camera.

ws_part4_15.jpg

I’ve cropped the image to a square, turned the image into an unlocked layer, and added a new layer underneath the image. I’m going to be making a radial gradient fill on the new layer UNDER the photo.

ws_part4_16.jpg

Turn the photo layer off and select the new layer you made under it. I’ve made my gradient fill and stretched it out a bit. I want a soft white under my subject.

ws_part4_17.jpg

I go back to the photo layer and select it and turn it back on. Then I change the layer blending mode to “multiply”. Anything that is pure white will drop out and the color from behind will show through.

ws_part4_18.jpg

It looks like this.

ws_part4_19.jpg

You can change the color, density, and saturation of this type of gradient fill with levels, curves, hue/saturation, etc. Here is a change up to the bottom layer with hue/saturation.

ws_part4_20.jpg

Here is the image with this change.

ws_part4_21.jpg

This isn’t the way to just drop a subject into a whole new location. You have to get into some layer masking and a few more steps to do something like that. These are just some simple steps to show you how to change things up a bit for images you want to make for your clients or promotional images you need to make for yourself. You can create the perfect amount of negative space to add logos, text, etc. If you are into textures you can then start adding those into some of these steps as well. Using the multiply mode on white backgrounds opens up new possibilities for you. Note – It doesn’t work the same on images with a black background.

For the next post, I’ll show a few lighting options you can have when shooting on pure white backgrounds. After that I’ll have a post asking for questions you may have. I’ll also be going through all the comments on this tutorial so far and answering those questions in one single post.

Then we are going to have a contest! If you are starting to shoot this stuff or have been, you can now begin adding your images to the Seamless & Cyc Flickr pool I have started. Let’s see how creative you get. I’ve filled up the pool with my visual pollution to get it started. You add the rest. I’ll have prizes for first, second, and third place. I’ll give you details on it coming up soon. Add your images that have been shot with any of the techniques we have discussed here when using a simple white background. If you are just using a white wall to start you can post those as well.

Continue Reading :: Part 5 Wrap Up, Questions, and Contest!

ETA – If you have questions about any of this, drop them in the comment section here on Part 5 of the tutorial. I will be following up on this tutorial with a new post answering all the questions at once.

Cheers, Zack

White Seamless Tutorial :: Part 3 :: From White To Black.

black_bg_04.jpg  

If you are just joining us, this is part three in a four or five part tutorial about the many uses of white seamless as a background material.  You can catch up by reading part 1part 2, and part 2b

We’ve taken our white seamless BG and made it pure white.  The task set before us now is to get a few more visual options out of that white seamless paper or simple white wall we are shooting against. 

When I got my first studio space I had few resources to fill it up with backgrounds and stuff that studios should have.  The very first thing I bought was a roll of white seamless paper.  I had to start using it with two lights.  One on the subject and one on the background.  That’s all well and good but I needed to have the ability to get as many looks out of that one background.  These are some of the simple and effective techniques I still use to get some different looks from a single background. 

The first thing you can do is simply turn the background lights off. 

zd3_0508.jpg 

The image above is the same exact photo except for the fact that I turned the BG lights off.  I shot one with the lights on.  Then one with the lights off.  Same settings on my main light and same settings on my camera.  Your white BG is now a medium grey. 

Here is a full length shot with the tile board removed. 

zd3_1298.jpg  

I removed the tile board because it can be a bit difficult to get it to blend seamlessly when you are lighting the BG.  It can be done you just have to finesse your light and shooting angle to the point where you no longer see the edges of the tile board on the floor and maintain a consistent tone of grey while still picking up a bit of reflection under your subject.  Currently I don’t have an example of that on hand.  I’ll dig for one in the archives and post it when I wrap this tutorial up. 

If you can wrap your head around things like inverse square law and feathering your light then you can begin to make that BG any shade of grey from black to light grey. 

Inverse square law is an equation that talks about math stuff about how light falls off over distance.  I’m a photographer.  I like pictures.  I don’t like physics. Inverse square law to me is like that quote about electricity that I’ve heard before… “I don’t know how electricity works but I use it everyday.” 

If you double your distance from flash to subject, you lose 75% of the light.  To me it seems like if you double distance then you lose half of your light but some dudes and some ladies (probably more dudes than ladies though) figured out that is not the case.  You double distance from flash to subject you lose 75% of the light.  Not 50%. 

In Myth Busters type of science that means when you double distance you lose 2 stops of light.  If you double one foot that means you lost two stops of light at the two foot mark.  If you double 20 feet… you lose two stops at the 40 foot mark. 

Let me say this now though… Before any of you get on here with your Texas Instruments graphing calculators to show me where I’m wrong on this… Take it to DPReview and fight it out there with the other measurebators.  I don’t care!  Like I said, this is some Myth Busters kind of science explanations. 

With a point light source like a straight flash it looks like this… 

inversesquare.jpg  

From f22 to f16 that is 7 inches.  From f5.6 to f4 that is 3.5 feet.  If your subject was standing where the f22 tick mark on the wall is and the white seamless BG was over there by the 5.6 tick mark then by the time you expose properly for the subject at f22 then your BG would be (16, 11, 8, 5.6) FOUR stops under exposed from your subject. 

Here’s the basics that a public school educated guy like me can understand.  If you get your subject some distance away (like 10 feet let’s say)  from the BG and your light source really close to the subject (like 1 or 2 feet away) then once you properly expose for the subject…. the light falling off toward the BG falls off to the point that your BG can be 2 or 3 stops under exposed from the subject.  The more you under expose the BG the darker it gets. 

Again… The larger your ratio of exposure is from your subject to BG the darker the BG gets.  The smaller the ratio gets, the lighter the BG.  

Huh?  What?  Yeah, I know.  It looks like this without any use of Photoshop. 

zd3_1259.jpg  

I’m going to post that same photo right after this explanation… 

For these two images I kept the subject the same distance from the BG.  He was about ten feet from the wall there.  For the image on the left the softbox was about 5 feet away from him.  Exposure on him was f2 or something.  Then I moved it in really really close.  Just outside of the frame.  Once I closed down my aperture to compensate for the light being much closer to him, the light ratio between his face and the wall was now a larger ratio thus making the BG darker. 

zd3_1259.jpg 

Still don’t get it?  Reading my explanation over again won’t help much because I think it confuses me as well so let me try to sum it up another way.  All you engineers out there are laughing your butts off at me because this stuff is elementary.  Like I said, I went to public school. 

Get your subject about 10 feet off of a wall and get your light source 7 or 8 feet away from your subject in a position that light is hitting your subject AND your background.  Make a proper exposure for the light hitting your subject and look at the white BG.  It will be a lighter shade of grey. 

Keep your subject right there and more your light in really, really close to your subject.  Like one foot away (just outside of your frame).  You have now changed the exposure so you are going to have to stop down your aperture until you have a proper exposure on your subject.  Once you have the proper exposure on your subject, that white BG will now be a darker shade of grey than image you shot before with the light 7 or 8 feet away. 

If you are reading this and don’t get it… Get off your arse and go shoot it.  You’ll see it pretty quickly. 

You can further eliminate light falling on the BG to get the BG to go darker and darker still until you just “blow it to black” as I like to say.  Or, you make dark with light.  I typically do this with feathering my light and getting my subject even further away from the background. 

When you “feather” a light you are positioning your light in such a way that it isn’t pointing directly at your subject.  Instead, it is pointing a little bit away from subject yet not pointed so far away that you are no longer lighting your subject.  You are just wanting the subject to catch the feathered edge of light coming out of your modifier.  Point that light AWAY from the BG yet still getting some on your subject. 

If you tweak your feathered light just right and have a good distance from your BG then you can take that white seamless (or just about any other color of BG) and it will become black. 

Here is a four light set.   

white_bg_02_setup.jpg  

Two lights on the BG, one light with a grid to light his arm, one light zoomed in to light his face.  Here is what it looks like on white… 

white_bg_02.jpg  

Remember how I talked about my philosophy in all of this is I light my subject independently from my BG?  With my lights on my subject set up properly, those lights aren’t adding any exposure to my BG.  So if I turn the BG lights off and just use that tight grid and a zoomed Vivitar 285 I get this… 

black_bg_05b.jpg 

I did NOT change the white background out for a black one!  I pinky promise!  I just kept that grid and that zoomed light positioned in a way that none of that light hit the BG. NOTE – I’m staying at my sync speed on my shutter speed to make sure I’m killing any and all ambient light falling on the BG. Shutter speed controls ambient light. Even though there was light in the studio when I was shooting, I was shooting at f8 at 250th of a second or there about so I wasn’t exposing any ambient light in these images with black backgrounds. 

black_bg_01.jpg  

For the image above she was about 15 to 16 feet away from the BG.  I had a big softbox pointing just in front of her.  Enough for the feathered edge to light her.  Then I had a second light add a bit of a side light for separation making sure that the side light did not hit the background. 

Grid spots are awesome.  You can use those things to keep light off of any BG you may be using like this… 

black_bg_04.jpg  

Grid spots have a small feathered edge of light.  You can point the main circle of light in front of your subject and just get their face into that feathered edge and it looks like this… 

black_bg_07.jpg  

You can grid a subject again, add a background light pointing toward your subject and get this… 

black_bg_08.jpg 

You can take a big ol’ softbox, move your subject away from the BG as much as possible (like 15 feet or so), under expose the whole thing just a bit and get this… 

black_bg_10.jpg 

Take it light grey… 

grey_bg_02.jpg  

Take it darker… 

grey_bg_07.jpg  

Set your BG lights to a low power setting and get them evenly positioned on the BG and match the BG exposure with the subject exposure and get a very even tone of grey through an image… 

grey_bg_06.jpg  

Position your light in just the right spot where you get just a bit of separation from dark shirt or hair to a darker BG… 

grey_bg_04.jpg  

Keep the light on your subject but OFF of your white BG so that the BG goes black.  Then double or triple stack some colored gels on your BG lights and set them to a fairly low power setting and you can now add color to your white BG… 

red_bg_01.jpg  

IF you let the clean white light from the subject light hit the BG when you are trying to gel it to a color, then you are going to contaminate that gelled color back there and you’ll lose the saturation of the color you are trying to achieve.  I used a grid spot in the image above to keep light just on the subject and off of the BG.  I kept him far enough away from the BG that the red light from the BG didn’t wrap around him and give me some funky color shift on the subject. 

White.  Grey.  Black.  Red.  Blue.  Whatever.  One background.  Many options. 

The next tutorial will be about what we can do with some of these images in post production.  I’ll show you things I do in 30 to 60 seconds of time that changes things up even more. After that I’ll post a few different lighting techniques for lighting your subject on the white seamless.  Then I’ll have a post where I’ll be open to questions in the comment section and I’ll cover the questions already in the comment section now. 

Then I’ve got something fun for us after that and that will conclude this tutorial!  You can expect for this to be all wrapped up this month.  My schedule is a bit hectic right now.

White Seamless Tutorial :: Part 2b :: Full Length With OneLight

seamless_part2b_01.jpg

I felt challenged today to see if I could shoot a full length portrait on a plain old white seamless background with a single battery powered light source. There is this thing I do with barebulb flashes that blows the background to white and I use an adjoining wall near the subject to catch light from the bare bulb to bounce back to light the subject’s face. The problem with trying to do a full length with a single light source is dealing with the light stand getting in the way. Positioning it out of the frame is a pain. You say four letter “f” words (like film) trying to keep the light stand out of the way and lighting the walls and trying to keep light from the flash off of the wall (edit – I mean subject). 

The challenge I gave myself today was to shoot without a light stand. I figured I would try placing the bare bulb flash on the ground behind my client and use those bi-fold cutter doors as reflectors to catch the light from the flash and bounce it back to the front of the subject. I taped the Sunpak 120J and Pocket Wizard with white tape to further conceal the rig in case I was in the frame. The challenge was to not have to remove anything in Photoshop.Here is the taped rig…

Here is the result…

Not bad really. A little flare around the ankles that is giving me a color shift on the legs. I can live with that and “fix” it if needed. Better than trying to remove light stands from photos. Here’s another shot with the same lighting scenario…

It was a slight PITA keeping separation of her light hair on the white BG. Just a hair of the “fill” slider in Lightroom helped bring the exposure of her face up. Here is wider shot showing a bit of the bi-fold doors acting as reflectors…

I was out of time so I didn’t try the same scenario with the tile board. I’ll try that another time. 

There is another way of doing this with a single light source but you need more power than four double “A” batteries and a pretty dang large light source. I’ll shoot one of those when I get back from my week teaching OneLight’s in California. 

Speaking of that, I have to be at the airport in seven hours. I’ll be working on the next part of this seamless tutorial on the plane. 

On a side note… 

Fellow photographer and all around amazing guy, Troy Stains, stopped by today while we were shooting. I have to share this image I shot of him. He’s pimp.  This was part of our shooting for the OneLight DVD coming out this summer.

White Seamless Tutorial :: Part 2 :: Setting Lights & Exposure

seamless_part2_01.jpg

We are now going to look at setting up a simple headshot on a pure white seamless background, or, “BG” for short during this tutorial. Click here for Part 1 of this tutorial.

The philosophy I have when shooting on pure white is that I want to light the BG and the subject independently from each other. Meaning; The light on the subject isn’t making a change to the exposure on the background and the light on the background isn’t making a change to exposure on the subject. As I talked about before, those cutters on the sides of the set are key to making this happen. The next consideration is keeping the subject a fair distance away from the background as well. In this first example my subject, Thomas, is about 11 feet away from the white seamless hanging behind him. The closer he gets to the background, the more likely it is that light reflecting off of the seamless is going to add exposure to him in the final image. The further I get my subject away from the seamless, the less light coming in from the background will get to him. I’ll talk more about that specifically in a bit.

For the sake of being as technical as possible for this tutorial I have wiped the dust off of my light meter and put it back into use. I rarely, if ever, pull it out when setting up this type of set simply because I’ve done it so often and I know what I’m looking for when I chimp. If you have a flash meter already, good for you! Pull it out and put it in the incident mode. If not, I’m going to give you examples of the visual clues I am looking for when I’m shooting so I know how to adjust my lights without using a flash meter.

For this set up I have two lights on the background. One on each side. I also have barn doors on these lights in addition to using the bi-fold cutters. Since my ceiling in here is so low and those white walls are so close to the set I use the barn doors to flag light from the BG lights off of the ceiling and walls. The light on camera left is pointing just left of center of the BG. Camera right light is just right of center of the BG. I want an even spread of light across the BG so that if I were to take meter readings from the left edge to the right edge of the seamless, I would get identical readings from edge to edge. If your BG is within a quarter stop from edge to edge you’ll be fine. If your BG has more than half a stop difference from edge to edge, position your lights in such a way to even that exposure out. If you don’t have a light meter, eyeball the dang thing and go for it.

For those of you new to lighting I am only going to be talking about exposure in terms of f stops. Shutter speed controls ambient light exposure and aperture (f stop) controls flash exposure. The ambient light in this scenario means nothing to me since I’m lighting everything with flash so my shutter speed is always going to be near my sync speed of 250th of a second. If you don’t know your sync speed you’ll have to RTFM. If you don’t know what RTFM is then you’ll have to Google that and ROFL. If you are lost on ROFL… how did you even get to this web page? Colon right parenthesis.

Also, these are always shot at my lowest ISO setting so that I have the cleanest images. No need to shoot this stuff at high ISO settings especially if you have some decent power coming from your strobes. If you are doing this with hotshoe flashes there can be occasions you need to up your ISO a bit.

For the subject I have one light source. For this particular shot I’m using a Westcott 50″ Apollo softbox. The light inside of the softbox is set to 100 w/s (watt seconds). For the pure white BG it doesn’t really matter what kind of modifier you use. Like I said, I’m lighting my subject independently from the BG so I choose my modifier based on the kind of light I want on the subject. You can use straight flash, an umbrella, a grid spot, a beauty dish, etc, etc. Actually, my favorite these days is a beauty dish. I just love that thing but for this, I chose a big softbox.

From my meter I’m getting a reading on my subject of f8 from that softbox (main light). To make that white BG pop I know that I need to have the BG at least 1.5 stops hotter than the subject. My target then is to get the BG reading to be f 11.5 because my main light on the subject is f 8. I’m going to expose for the subject at f 8 once I shoot a frame. I don’t really want the BG to be any more than 1.5 stops hotter than the subject’s reading. You’ll see why in the examples below. f 8 on the subject and f 11.5 on the BG is my standard set up. You can set the ratio anyway you want it. If your main is f 2.8 then you want the reading on your BG to be f 4.5. If you get f 5.6 on your subject then you want the BG to be at f 8.5. Nerd note – If the EXIF data is still in these images and you’re reading it you’ll see I actually exposed at f 9. My meter is about 1/3 of a stop off from my camera.

Let’s look at a properly exposed image first ::

seamless_part2_02.jpg

In the image above I have a nice white background, no significant amount of flare coming back into the lens, no chromatic aberration (CA) around the edges or in the hair, a good exposure on Thomas, and I’m getting just a bit of “wrap” on the shadowed side of his face.

For that “back of head” reading I took my meter and placed it at the back of his head and pointed it toward the white seamless and took a reading. This is measuring the amount of light coming back to the subject from the BG. The more light coming back, the more wrap, and possibly more flare, you are going to have on your subject. That “wrap” is seen as a highlight on the camera left side of his face. That is coming from the light reflecting off of the white seamless. Some folks HATE wrap and work to eliminate it. Some folks like to have more of it. Personally I go both ways. Country AND Western.

There are times I want it eliminated. Maybe I want a really deep shadow on the side of the subject’s face. Lighting wrapping in from the back would fill that shadow in too much. Another example of the need to eliminate the light wrapping around your subject is when you are shooting someone wearing pure white. I want to keep a very clean separation of white on white. We’ll see that coming up in a minute. Sometimes I love to have more wrap because it accentuates the subject’s facial features. Most of the time though I’m fine with just a bit of it. The wrap above is something I won’t say cuss words about and I won’t lose any sleep tonight because of it.

If you want less wrap, move your subject further away from the BG but keep the same 1.5 stop exposure ratio from subject light to BG light. If you want more wrap, move your subject closer to the BG while still maintaining the 1.5 stop exposure ratio.

For those of you without a flash meter here are some examples showing you when your BG lights are over or under exposed. These are shown with the idea of you have a good exposure from your main light on your subject. Find that exposure first by turning off your BG lights and shooting a series of images of your subject with just the main light on. Remember, we are lighting the subject independently from the BG. If you have this set up correctly then you can take a shot at the proper exposure of your subject with the BG lights off and then with them on and your subject will remain properly exposed in both images with the exception of some wrap coming in from the BG when those lights are turned on. Make sense? No? Shoot pictures with your BG lights off and find the right exposure on your subject from the main light. Then turn on your background lights and adjust the power of those up or down to get a clean white BG.

Here is an example of when your BG gets too hot and starts giving you problems.

seamless_part2_03.jpg

I had set my main light on my subject and got a reading of f 8 from it. With my BG lights cranked all the way up to full power I’m now getting so much light off of that BG that it added a stop to the meter reading of my subject. I suspect that the face of my softbox was even acting as a reflector to help add to that extra stop of light coming in the front. Looking at the image above it is pretty evident that the BG lights are set too high in power. Look at all the flare coming in over his shoulder on the camera left side of the frame and look at the overall loss in contrast in the image. I talked in the previous post about some lenses work better than others. My 50mm 1.8 lens shoots images that look like this on a properly exposed set. So if you are dead sure confident that your light ratios are correct and you get that much flare and loss of contrast, try another lens.

Here is an image with the BG underexposed.

seamless_part2_04.jpg

There is nothing wrong with the image above here. In fact, you may want some density in your BG from time to time and we are going to talk about that in the next part of the tutorial. BUT… we are talking about setting your BG exposure properly to get a PURE WHITE background in your image and that BG ain’t white. If that is your image and you want it white, the curse words show up in post production. If this is what you are getting then you simply need to up the power settings of your background lights.

Two additional things to look at in this under exposed BG image :: Notice the lack or wrap coming in from the BG and how much darker the shadow on the camera left side of his face is. Also notice that my lights aren’t set to give me a dead even exposure across the width of the BG there. One side is a bit hotter than the other. Each light is set exactly to the same power setting but the camera left side is a bit hotter than the camera right side. This is a visual indication that I need to change the position and/or direction of my BG lights so I’m getting even light across the BG. It isn’t that big of difference here. But it is noticeable and there are times when I want density in that BG and I want it to be perfect from edge to edge in continuous tone. Again, we’ll talk about that in the next part of the tutorial.

Once you nail your exposure and everything is set correctly, you can shoot someone wearing a black shirt on a white background and have them switch to a white shirt on a white background and shoot the same exact exposure and maintain separation.

seamless_part2_06.jpg

Let’s take a look at a series of images with the lights in different states of being on or off.

seamless_part2_05.jpg

See that second image in the series where there is a tad bit of light hitting the front of Thomas? That is light coming off of the BG, hitting the ceiling, and adding a slight touch of exposure to the front. If I had taller ceilings and / or my ceiling was black, I would have more of a silhouette there. I’m seriously considering painting my ceiling black but I haven’t decided if I really want to stay in the space beyond my lease. I want a cyc wall again damn it and I’m not going to build one here! Anyway……

Also notice the “all lights off”. I wasn’t shooting in pitch black but an exposure of f 9 @ 200th of a second at ISO 100 made a black frame because the studio is not that dark but not bright enough to have any ambient exposure come into the final frames I’m shooting. If I had some really hot spot lights on the BG or a bright window near my set we may see a little something in that image but not much. Once those strobes fire it would kill that kind of ambient light. So changing your shutter speed all up and down here doesn’t matter. Just set to your sync speed and adjust exposure on your camera by aperture only. You further change exposure by changing power settings on your lights…. but to reiterate. At camera level… set to your sync speed and just adjust f stops.

So that’s a basic headshot. You don’t have to have a roll of seamless for this application. Any old white or off white wall will do. Let’s look at a full length next. I’m going to cry 7 tears and say 3 or 4 cuss words as I visually take you back to my last studio with the big cyc wall. That thing was bigger than my house. Developers came in and bought the place up and I can have it again in a few years at 3 or 4 times the cost per square foot once they pimp the place out and do stupid things to it. Like… Bring it up to code and stuff and take the lead out of the water.

I pull this off in the new space pretty easy until I have a band of 4 or more in front of me and I’m restricted to the 9′ width of white. It can be done with only moderate cursing. I’ve shot a family of 7 on a 9′ seamless before. For now let’s look at just shooting a full length of one person. Here is the back of the set.

seamless_part2_07.jpg

This is what the back of the set looks like. Notice that straight shadow line the bi-folds are making. I keep my subject in “the shade” of the bi-fold doors so to speak. Also note that I hang the tile board out into the BG light area just a bit. The BG lights blow that little edge out so it isn’t seen in the final image and I don’t have to go into Photoshop to remove the hair line it creates if I don’t have it hanging out in the BG light.

Here is the front of the set.

seamless_part2_09.jpg

Note that without that tile board, the white floor area is grey. Getting a subject standing on white paper and shooting a full length shot so that the floor and the BG are all white is a pain in the arse. You can do it but it’s a different way of lighting that I just don’t do. Call me lazy but $20 worth of tile board makes life easy. And no… those Home Depot work lights in the back are not being used on this set. This is three lights firing. Two on the background and one on the subject.

Let’s add a subject and a big industrial fan.

seamless_part2_10.jpg

I show the image above to give you another glimpse of what the floor would look like without the tile board. It would be grey right up to the shadow line the cutters are creating from the BG lights. The tile board acts like a mirror in that you are seeing a reflection of the white BG in it.

Here is an image straight out of camera with only adjustments being made to color and contrast.

seamless_part2_a.jpg

Clean. Simple. Effective. Done right on set and in camera so I don’t have to cuss like a sailor in post production. Notice the good separation of the white dress on the white background. Notice the nice little wrap on the camera right side of her face. I really like the wrap here and would not have worked to eliminate it. It was just enough to have some wrap but not enough that I lost the edge separation of the dress.

That wraps up Part 2 of the tutorial. Thanks to Thomas for being my exposure subject today and thanks to ya’ll for the comments and links and all that so far! Once I finish this tutorial I’ve got something kind of cool planned for all of you.
