Backscattering: Underwater cameras that have a flash on the camera body may cause pictures to have backscattering. Backscatter is caused by the light from the flash going straight out from the camera, hitting particles in the water, and then being reflected directly back into the camera. If the flash was above, below, or to the side of the camera the light would go out at angle, hit the particles, and come back at the opposite angle. The reflected particle light would not come back to the camera, thus reducing or eliminating backscatter.
The following 3 photos were taken in West Palm Beach, Florida in January 2001. They show the affects of backscattering:
This photo was taken in water that have few particles such as sand, silt, etc.
The diver: PADI Instructor Mike Masloski diving in about 80 feet of water. This visibility here was reduced due to sand in the water. Notice the round circles of light cause by the flash bouncing off of them.
This photo was taken on a shipwreck in West Palm Beach. It was taken in the same stirred up water as the picture of Mike Masloski. Because it was taken as a closeup, the effect of backscattering is greatly reduced.
