Nolan was photographed with the Olympus 45mm f/1.8 lens on the Olympus OM-D E-M5 camera body, and lit with an Alzo Digital Pan-L-Lite. While Hannah and Paris were also lit with this same light, I had a diffusion screen over the front of the light. This makes the source larger and softer. In Nolan's case, though, I removed the diffusion and closed down the barn doors on the light. This creates a harder light, and you can see the harder edges on the shadows. This light works really well on Nolan.
Many thanks to Hannah, Paris, and Nolan for being our willing subjects that day.
