Underwater Strobes:
Part 4. Digital TTL
In the days of film, when TTL was commonplace, underwater camera
manufacturers were quick to embrace its benefit. Yet in the
digital age, very few underwater system offer true TTL flash.
There are exceptions, like Ikelite and Olympus to name two, but
for the most part today's underwater camera systems rely on
varying the strobe's output manually. Sea & Sea offers a
TTL converter add-on that retails for $500, but for the most part
photographers must rely on a manual control knob to dial in the
correct amount of flash.

Though the lack of this option
is surprising in view of how many photographers rely on flash TTL,
it's not as disappointing as many would believe, especially in
view of the shortcomings of TTL flash photography previously
mentioned. |

Why? Because the camera's viewer
allows photographers to see the results immediately, and flash
exposure problems can be corrected on the spot. I actually
prefer this method, since it gives the photographer more control,
allowing him to dial in just the right amount of light.
