I did a photo shoot with model, Katie Jo, this past weekend for publication. However, between "looks" we decided to do a straight forward head shot. The goal was to give the images to the hair stylist, model & MUA for their portfolio. I wanted to do simple lighting that focused on Katie's face and subtly on her hair.
The background for the setup was a piece of black 3'x4' foam core clamped to a flexible arm on a Kupo C-Stand. Simply raised it up so it was behind Katie. Lighting was an Elinchrom D-Lite 4 studio strobe with an Elinchrom 8.25" reflector. The light was diffused with a 30 degree grid. This was mounted on a Manfrotto boom stand.
The light was set about 4' away from Katie camera right about 7' high. I pre-flashed the light while Katie was standing to the side to make sure the circle of light from the gridded strobe landed square in the middle of the backdrop. I wanted the majority of the light to fall on my model's face, and drop off quickly.
Light was metered at f/9 with my Nikon D600 settings at ISO 160, speed 1/160 of a second. I ended up stopping down to f/10 during the shoot.
Really, that was it. We only took about 4-5 minutes between each look to crank off about 10 shots per look.
