Thanks to Evolution Martial Arts for letting me invade their Octagon and photograph some of their fighters. For this set-up I used 3 strobes. 2 in the back for rim light with a reflector and grid. The main key light was an Elinchrom BRX 500 with an octabox.
I used Adobe Camera Raw and Photoshop CC along with NIK software and Alienskin plugins.
