“HOLD it.” Jonathan Leder was standing behind a tripod on the porch of a musty, wood-shingle house in West Kill, N.Y., pointing his camera at a 19-year-old model, Britney Nola, who was wearing nothing but an unbuttoned pink shirt from American Apparel and a pair of slouchy blue socks.

Ms. Nola, who bears a passing resemblance to a young Brigitte Bardot, stood frozen by a screen door. Behind her, the bedroom evoked the faded glamour of this Borscht Belt region  wood paneling, wood-grain television console and unironic deer heads.

“Come closer,” Mr. Leder instructed Ms. Nola, as the two tried different angles. “Tilt. Head this way.” With the exception of Mr. Leder’s 2-year-old son, Jack, who would occasionally stumble into the frame, the house was surprisingly quiet for a photo shoot, especially a pornographic one. There were no photo assistants, no special lighting, no bunny suit in sight.

Mr. Leder continued snapping Ms. Nola  raising her head, facing the sun, lifting a leg  until his camera suddenly stopped clicking. He looked at his 1965 Canon Pellix and spotted the problem. “I’ve got to get some film,” he said.
