Stonefish
I’m almost ready to commit to a more reliable external flash. This would be major money and more to try to keep dry and safe. My on-camera flash is helpful. It certainly works during a night dive. I can get very sharp images in available light. There is a definite boost to the color when flash is in play. My question? How do fish see? You may notice the fish eye bulge to the lens of the eye. And the pupil is dilated to catch all available light. But is the color spectrum of the fish eye the same as mine. In other words are colors drab and muted underwater or are the fish perceiving the bright brilliant riot of color I capture in the flash image? Help! I need a fish translator. I suppose it would not help to ask if some fish are colorblind.
