Dustin Herlich submitted this image taken with a Canon A620 in an underwater housing, with an exposure of 1/60sec at f/4, no ISO recorded. Dustin set the camera to macro and timed his shot just as the fish would come in to strike the camera. The colors are rich and the background adds to the image as does the texture from the material to the side of the fish. The fish is a scene stealer and Dustin has done a beautiful job of preplanning and taking into consideration the underwater lighting when determining his settings. I wouldn’t change a thing.
