What color disappears first underwater? Water absorbs different wavelengths of light to different degrees. The longest wavelengths, with the lowest energy, are absorbed first… Even water at 5ft depth will have a noticeable loss of red.

Why do I lose Reds when I go underwater?

  • If you are 10ft underwater, and you are viewing an object 10ft away, the light has actually travelled 20ft, and all of the reds will be filtered out. Likewise, if you light up an object with your strobes 5ft away, the light has to travel 5ft to the object, and 5ft back to your lens, for a total of 10ft. This is a significant loss of reds.
  • Underwater, waves travel differently, and some wavelengths are filtered out by water sooner than others. Lower energy waves are absorbed first, so red disappears first, at about 20 feet. Orange disappears next, at around 50 feet.
