Some Facts About Underwater Photography
1. Water will absorb various colors, such as red, orange, yellow, etc. That's why your underwater photography looks blue when you don't use a flash or strobe. The deeper you dive, the more color the water absorbs, so we often say that the depths of the sea are black.
2. A compact camera with a built-in flash can be used to add color to your underwater shots.
3. Professional diving photographers usually buy an external flash or strobe as a means of adding color.
4. Water will reduce contrast, color, and sharpness, so when shooting underwater, your camera should be within 1 meter of the subject, or even closer.
