I took the guys from You Me At Six around Union Square for a portrait session in New York City.
(Nikon D3, 24-70 lens, ISO 400, 1/250 sec, f/5.6)
This is a two-light shot of them emerging from the subway. One Nikon SB-900 is being held right over my shoulder and fired up into a white dome over their heads. It provides an even fill light.
The second light is being held by my assistant above the subway sign and pointed at their backs. I knew I would get flare, but I like the way it looks in this case.
I did the black and white conversion in Nik Silver Efex Pro.
