Naked vs clothed

Hamm's series "Naked Faces," which he started in 2016, is comprised of side-by-side images of 43 people, all of whom were photographed while wearing clothing and while naked. But, rather than photographing their full bodies, Hamm focused on the subjects' faces so the viewer can analyze how a person's facial expression differs while they are clothed and unclothed.

While Hamm has shared all 43 images on his website, he has yet to reveal which photos show clothed subjects, and which were taken while they were naked.
