The Sealife SL961 is a powerful underwater strobe light. Since the strobe will fire with four different pre-flash settings, as well as no pre-flash, it will work with any underwater digital or film camera that has a built-in flash. Since water absorbs the red and yellow light spectrum resulting in blue pictures you need a flash to bring out the intense colors of the underwater world. It also reduces the backscatter problem that normally will occur when using a camera with a built-in flash.
When using the Auto Mode Setting, the strobe automatically adjusts the brightness for optimal image exposure. You can also shoot in manual mode. The strobe features variable flash control enabling you to dial the flash power up or down for better image exposure. Also included is a flexible, rubberized arm for easy aiming and a sure grip. This will allow you to position the flash for the best possible lighting.
