Inside shot

This is a large room inside the Hilma Hooker, a famous wreck on Bonaire. I got the idea for the shot from another on Wetpixel.com, but this one worked just by luck. Turned around and shot. Lighting was right, time of day was right for the light to hit the wall, and diver was in the perfect spot with her light. f 4.5 at 1/20th, no strobes. But what's the right Categorie? :-)
