"We see thousands of eyes in our life but never suspect about the structure of the iris," Manvelyan tells RFE/RL. "It is very beautiful and astounding. The surface resembles the surface of other planets, with craters, rivers, and valleys. It looks like something from another world. Every time I photograph the eye, I feel myself traveling through the cosmos."
Manvelyan, who has a doctorate in theoretical physics, won't reveal his technique, saying only that "maybe every photographer tries to shoot eyes -- the windows of the soul. I am not an exception to this rule, but I was lucky enough to find an interesting way to do that."
Manvelyan has also focused on the eyes of animals, which he says pose particular difficulties.
"Sometimes I need to work for an hour trying to catch the still moment," he says, stressing that no animals (or humans) are ever harmed during his studio sessions. (A few of his animal eyes are included in this gallery.)
As for his next project, Manvelyan says he'll continue with his eye portraits but is interested in exploring the more down-to-earth world of wedding photography.
