Renowned underwater photographer Wes Skiles died Wednesday while diving off Florida’s east coast.

Skiles, 52, of High Springs, was pronounced dead after he was found motionless at the bottom of a reef Wednesday afternoon.

Skiles had been diving with others and filming underwater about three miles east of the Boynton Beach Inlet, said Sheriff’s Office spokeswoman Teri Barbera.

Skiles apparently alerted the other divers that he was ascending because he was out of film, Barbera said. The others continued in the water but later decided to ascend.

“On their way to the surface, they found him at the bottom of the reef motionless,” Barbera said.

The man was rushed to the surface, and CPR was administered.

Barbera said the man was taken to an area hospital and was pronounced dead.

Skiles was instrumental in helping to map the caves and develop safety rules for diving at Ginnie Springs Resort.
