For Podie. Underwater pictures gone wrong!
Discussion
OK, Podie, I've dug out a few underwater piccies that have gone wrong. I've added underneath what the camera settings were, so you get an idea! All the pictures were taken at 200 ISO.
A couple of humbugs underexposed. Yes, I could tweak in PS, but it comes out looking pretty mediocre.

f25 @ 1/60th Strobes f16
A wreck shot that is all washed out at the top. Exposed correctly up north, it would be totally underexposed down south. This one really went pear-shaped!

f4.5 @ 1/125th Strobes f8
An over exposed nudibranch. The white on the top of his noggin is all washed out.

f22 @ 1/60th Strobes f16
A pair of underexposed nudibranchs

f22 @ 1/125th Strobes f16
A school of batfish. Taken too far away (damn things kept swimming away from me
), so just didn't come out right.

f6.3 @ 1/100th Strobes f5.6
Doubt there was anything wrong with the settings here, but I suspect the flash bounced off the coral above these angelfish, so never actually got anywhere near them.

f11 @ 1/60th Strobes f11
White subject (small spotted moray) on a sandy background, taken at night. Even with the settings I had, it was totally overexposed. Grrrr.....

f25 @ 1/400th Strobes f22
A chufftastically enormous Spanish Dancer (kind of nudibranch) about 10 inches long, taken at night. Problem here was that the subject was too big for the lens (60mm macro) and I had to be about 3ft away from it, which affected not only the exposure but also highlighted the crap in the water (backscatter). Regrettably I didn't get a decent shot of it.

f16 @ 1/200 Strobes f16
Hammerhead shark at 150ft. Too far away, too dark, you get the drift!

f8 @ 1/60th Strobes f8
A coral head in shallow water. I basically over exposed the image...

f5.6 @ 1/125th Strobes f8
So, there you have it, a snippet of how it can go pear-shaped. s
t happens, same underwater as above! Even I'm not infallible! 
hope it's of some use!
