Take any random underwater photograph and it has made use of a submersible flash unit also known as ‘strobe’ or just ‘flash’. Understanding strobes or Flash is a very essential part of underwater photography as they are the source of illumination.
- Need for Strobes
Underwater photography is all about dim waters without the lack of strobe. As water is dense, ambient light levels are quite dim. This is where strobes come to rescue by providing high intensity light that illuminates the subject. A complete palette of colors within the angle of coverage is provided by a strobe.
