I currently working on a recruitment project for SMPD and shot this yesterday.
Camera used was a Nikon D750 with a Nikon 85mm f/1.8 G lens. Settings were 1/125 sec at f/4.5 and ISO 1000.
Lighting used was one white LED bulb in a strip box soft box to light him from the back, and a Savage LED wand to light him from the front. The backdrop is a foldable Kate backdrop.
