Recently I had the honor of photographing Professor Jeff Lichtman of Harvard University for the third time. In each shoot, I have photographed Professor Lichtman with a microscope. I wanted to continue the theme on this assignment. His current microscope is one of a kind microscope that produces the most amazing images of the human brain. However, it looks like a large refrigerator. To make image more interesting and include a visual of his work, I projected one of his images on his microscope.
We had 2 hours including set up time to produce three situations requested by the client. I knew the one with the microscope would be the most difficult. I always start a shoot with the most difficult shot. The other 2 portraits requested were one in his office and another on the stairs.
I had the Professor show me his lab and we discussed ideas for the photographs. I told him we needed about 20 minutes set up time, and suggested he might want to go back to his office to work. There is no reason for the subject to watch you light. People have a limited amount of time set aside to be photographed. The less of their time I tie up, the happier they are in the photographs.
As I constructed the photograph, I had my assistant stand-in for the subject. The first few test frames were shot available light using a 17-35mm lens at 17mm ISO: 3200 F8 & 1/40.
When lighting a photograph like this I, add 1 light at a time. To light my subject I used 2 Dynalite Baja 400WS strobes. One on his face and one as the hairline light. The hairline light also gave me separation from my background. The Baja has a build in battery and no cables for me to trip on! Both strobes had a 10 degree grids to control where the light was aimed. To further control my light, I put Rosco FotoFoil on the side of the strobe closest to the background to prevent light spilling on the microscope.
To create the background, I attached a projector with a wide angle lens to a computer and projected one of the Professors slides. The key to projecting images on a background is not having any light from your strobes or any other light source hit the area with the projection. When I do a photograph like this, I always turn off the overhead lights. The room was dark when I was shooting. I had to use the flashlight on my phone to focus. Make sure your modeling lights are turned off.
We moved projector and adjusted its hight to project the Professor's research on his large white microscope. The projector was placed to the right of the Professor, 2 ft off of the floor.
To determine exposure for the background I used the in-camera meter. With the camera set on manual I set the aperture to the same f stop as the strobe reading and lowered my shutter speed until the exposure from the strobes in the foreground and the ambient light from the projector were the same exposure. The strobe f stop was determined with a Sekonic 478 meter. The final exposure was 2.5 seconds shot at f11. Jeff was lit for duration of the flash, while the background burned in. The image was shot on a Nikon D810, a Nikon 24-120 lens on an Induro tripod and Nikon cable release.
Equipment Used for the shoot:
Rosco Rick Friedman Location Lighting Kit
2 Daynalite Bajas Portarble Strobes with 10 degree grids
Nikon cable release
2 Light stands
Sekonic Lightmeter 478
Extention code for the projector
I love photographing academics. I find it fascinating to work with some of the world's greatest minds!
