The majority of the photography for which Cohen is known is shot in the Scranton/Wilkes-Barre metropolitan area (also known as the Wyoming Valley), a historic industrialized region of northeastern Pennsylvania. Characteristically Cohen photographs people close-up, using a wide-angle lens and a flash, mostly in black and white, frequently cropping their heads from the frame, concentrating on small details.[7] He has used 21 mm, 28 mm and 35 mm focal length, wide-angle, lenses and later on 50 mm.[8] Cohen has described his method as 'intrusive';[9] "They're not easy pictures. But I guess that's why they're mine."[10]
Discussing his influences with Thomas Southall in 2004[9] he cites ". . . so many photographers who followed Cartier-Bresson, like Frank, Koudelka, Winogrand, Friedlander." He also recognizes the influence of Diane Arbus.[10] Whilst acknowledging these influences he says: "I knew about art photography...Then I did these outside the context of any other photographer."[10]
