Good Illustration Of Flash Range In Water

[sabbath999]

I find the following picture interesting not because I think it is particularly good but rather because it clearly illustrates both how short the range of a dual strobe flash system is underwater and also how clear the water was (I did no backscatter elimination whatever... particles in the water flash white under strobes) taken at about 20 feet under at the base of the mooring ball for the boat in Kona. The complete loss of color shows the areas of coral that the flash didn't hit.

Water is about 600 times denser than air, which cuts down flash range to less than 10 feet even with powerful strobes.

wow. that is clear!! how deep? also, you using white or red strob? and how would strob colour effect your range?
