Digital cameras, and especially consumer cameras, have difficulty acquiring autofocus lock in dim lighting. Since light is removed by the water column, in many diving situations, it is beneficial to have a supplementary light source to help the camera focus. A bright focused light source is good for spotting, but it can be a problem as it may show up as a hot-spot in slower exposures. The solution is to use a lamp with a diffuser that spreads out the light in an even pattern. One such light is the FIX LIGHT manufactured by Fisheye in Japan . Wetpixel received this light for review and testing and I am happy to report the results.
