canon 15mm fisheye help needed

[Shamanix]

Hi Folks!
Ok...just got back from Egypt and was having troubles trying to take pictures at night.
My setup: canon 50d,sea and sea mdx-40 housing,canon 15mm fisheye lens.also i had 2 strobes: sea and sea YS-60 and sea and sea YS-90.
At the begining i was using only one strobe but was having difficulties to take pictures because camera wouldnt focus(automatic focusing plus dark) so i helped myself with the torch just to shoot the picture.The pictures would come out pretty much white (well overexposed).Next time i didnt take a strobe with me-used only torch(something had to be done differently).Pictures would come out much better but by far not as good as they should be.Torch had a very small light angle so it begs the question:
Do i need to take just the light under water and forget the flashes?if so,which one would you recommend?
What setups do you use for night diving with canon 15mm fisheye?and the settings on your camera?

Shooting wide angle at night is very tough. Normally very wide angle photos use ambient light (the sun) for illumination since no strobe can light up anything more than a few feet away. If you want to shoot CFWA then you need a good focus light and use the strobe to illuminate your subject only (the background will be dark)

yes...even at day time im geting too much light.especially with sand.it reflects the sun and pictres coming out like fish has auras i never used 15mm wide angle lens before so it kinda was a challenge at the beginning.it takes beautifull pictures but you have to get really close to things to be able to get the most of it. this picture was prolly the best ive done at night.if it would have been sand at the background then picture would have been litterally white.

You should be shooting in manual mode, this looks like one of the 50D automatic modes. Set your camera up in manual mode at 1/200 sec shutter and f:16 aperture. Set your camera up for manual flash and set the strobes to manual mode.
Everything then will depend on how you set the strobe power.
