White Out

I recently organized a photo-shoot at Faith Blackwell’s studio in the Stutz Building with model Olivia Ogden. Shooting with me were local Indianapolis photographers Faith Blackwell & Laura Poland. The theme for this shoot was High Key. This is a technique that I wanted to try, for no other reason than I hadn’t tried it and it looked kind of cool. After reviewing multiple High Key images, reading up and organizing the location and model, I gave it a go.

The effect to be achieved in high key is to overexpose the background so it’s completely white. There are several ways to get this effect but I planned to accomplish this effect using multiple studio and speedlights to throw as much light as I needed on a white background to over-expose it to the point of where there were no pixels at all.

Faith’s studio has one wall completely white. Since there is a dark grey floor I simply taped with white tape a 6 foot piece of background paper against the lower part of the wall and swept it out over the floor about 4 feet. I then used 2 Nikon SB-600 speedlights on light stands with a white umbrella. The setup faced the wall set back about 3 feet. Both speedlights were triggered with Elinchrom Skyport universal triggers. Speedlights were set at ¼ power. The goal was to use the umbrellas to broadly throw a diffused light against the white wall.

I then set up 2 Elinchrom D-Lite 4 strobes with softboxes set at approximately 1/3 power 45 degrees both sides of the background approximately 6 feet back. The D-Lite 4’s were triggered with internal Elinchrom Skyports.

During the shoot I varied the power of the softboxes mainly to backoff the fill lighting. The goal of these lights was to provide an even focused light to be thrown on Olivia. I was thinking originally using just ambient light or just one softbox to get move shadow, but I went with the wrap-around lighting. In hindsight I should have used less light on my model. We also used a hand held diffuser in several shots to eliminate glare from the ambient light coming from the window.




All shots were taken with a Nikon D300s in manual mode. White balance was set to flash although I was shooting in RAW. Initial settings were shutter speed at 1/200, aperture set at f/5.6, and ISO at 400. I varied all settings throughout the shoot. All shots were with a Nikkor AF-S 24-70mm f/2.8 G. I varied the aperture throughout the shoot.

I had asked Olivia to bring several changes of tight fitting clothes one with a dark top and one with a light top. Minimal makeup. The 3 of us then took turns shooting away for about 1 ½ hours. As always Olivia made our work simple by easily transitioning from pose to pose.

Near the end just to switch things up we asked Olivia to run a series of poses infront of a large south facing window. This provided sufficient ambient light as the sun had moved well overhead. We added fill light with one Elinchrom D-Lite 4 set as ¼ power and bounced some sunlight using a piece of white foamcore board.

Overall, it was a fun shoot doing both full body and headshots. We easily achieved the desired high key effect with minimal issues. The speedlights did the trick providing a very even exposure against the white background. Personally, I like the full body shots the best. However, if I do this effect again I would definitely back down the light being thrown on the model or vary the power of the light on one side so I can get shadowing and therefore more depth to the model’s face. Of course I could do the shadowing post processing, but it’s not the same.



Tip and after-thoughts:

• Build the light. For my shoot I set up all 4 lights in addition to the ambient light in advance and did test shots using all 4 lights. Next time I would start with the lights on the background, shoot some test shots of the model, add 1 strobe for the key light, take test shots, and then add a second strobe for fill light. I would then vary the power of the strobes to get different shadowing.

• For high key your histogram is important but a bit misleading. Because you have the background overexposed you will have a large peak on the right side of the histogram. Therefore, about ½ way through the shoot I switched the “blinkies” on and this gave me better visibility if I was blowing out the models face which I didn’t want to do.

• If possible shoot tethered. I think I could have locked down my setting much quicker if I had a bigger visual image as soon as I shot. I’ve shot tethered before, but didn’t think about it during this shoot.
