This week’s “Tuesday’s Tips” is from an assignment I shot at the MIT Media Lab in Cambridge, MA. The MIT Media Lab is a hub for innovative creations and one of my favorite places to photograph. I was at the Media Lab looking for interesting projects to photograph when I met Thad Starner who was working on wearable computing. Starner is now a professor at Georgia Tech. The idea for this shoot came about when Starner showed me a pair of glasses that had a computer monitor in the center of one lens, which he connected to a small computer in his pocket. With no preplanning, lighting eyeglasses can be difficult. This is how we did it on the fly!
Little did I know this was the beginning of “Google Glass“.
The lighting on this photograph is 2 strobes and 2 computer monitors. I had to match the brightness of the two computer screens to determine my exposure, matching the brightness of the large monitor in the background and the small computer screen embedded in his glasses. To obtain the exposure I used the meter in my camera. I needed a lot of depth of field for this shot, so that glasses and my subject were in focus. My focal point was Starner, seen through the glasses. The glasses were clamped to a light stand with a Manfrotto Superclamp. The main light was Dynalite 800 power pack and a Dynalite head with an extension tube, a grid holder on the end of the extension tube, a 10 degree grid and a sheet of Rosco Tough Spun over the grid to soften the light. I really needed to control my light on the subject, so there was no light spilled on the glasses or the screen behind the subject. Just off set, on the right side, I set up a speedlight with Rosco yellow gel and a snoot made of Cinefoil to outline the frame of glasses with color. The Cinefoil snoot was brought down so it was about a 1 degree opening. When making snoots out of Cinefoil, which is black tin foil, you have flexibility to make it any shape you want with any size opening, giving you great control over your light. To determine the exposure of both the speedlight and the Dynalite, I used a Sekonic lightmeter. If you are mixing speedlights and studio strobes, your speedlight needs to be on the manual setting (NOT TTL).
Happy Shooting, everyone!
