I bought my first strobe in 2010. It is a Sea & Sea YS-110α (Black). Japanese brand, Made in China 
Need a much brighter alternate light source. Something much more brighter than my dive torch.
According to the experts & books, this alternative light source is absolutely essential to bring out the true colours of the marine animals. To make my subject pop!
Back in school, science taught us that as we go deeper under the sea, colour will be lost because the density of the sea water will reduce sunlight penetration.
As a guide, here's a table of what colour will be lost at which depth:
3 meters, RED diminishes.
5 meters, ORANGE will go.
10 meters, YELLOW is gone.
18 meters, GREEN is gone.
25 meters, blue green is going.
30 meters, only BLUE remains.
I can't wait to try it out during my next dive trip. November 2010, I am going to the exotic Malapascua island located in the Visayan Sea, Cebu, Philippines. This gallery page will contain the photos from that trip & beyond.
