Adding these filters on strobe enables to reduce color temperature of strobe light. Two different grade filters deliver strobe light at color temperature 4900K or 4600K from original 5500K and each grade filter has non-diffuse version at same power output and half stop diffused version which increases beam angle to 110 degree.
These filters have been designed on totally new concept to control color temperature of underwater strobe to extend range of underwater imaging expression.
Reducing color temperature of strobe light will yield following effects;
Sample image processed RAW file at color temperature 4600K. Changing color temperature adds vivid blue on back ground water.
