underwater

[ETsd4]

Intensity of exposure ratio for algae at aug - sep 1997: 1997, 13.aug - 13.sept

As has already been said by TheBeast this underwatercolor changes then with the daylight, oceandepth, your actual diving depth, etc...

- The more clouds => the darker
- The lower the sun => the darker
- The deeper the ocean => the darker
- The deeper you dive => the darker
- The more algae => the greener

And one thing must be also clear, when the time/season will change then this colorszone-areas and the color will also change. This distribution of colours are pretty much accurat for aug-sept but not for jan-feb for example.

Bet at night, with no moon you can see only a black surrounding and your visibility is about 2 or 3 meters.
