Some photos I was tasked with taking of a bodybuilder a few days ago before he's goes to competition. I always forget to take pull-back shots to show the lighting setup. These were lit using a three light setup (a large softbox with a grid for the main light, and two strip boxes with color gels, also with grids, for the edge lights. Also a fog machine because why not. The black and white shot was lit using only the big gridded softbox. I use a rental studio so I honestly don't know the exact measurements for the modifiers.
