Contrast is exactly what your camera needs.
Scotty eluded to the nomenclature of the camera controls, but allow me to expand a bit
first and foremost, black froggies are tough to shoot. When i am composing a photo of frogfish in particular, there are a couple things i want. The eye has to be tight, lure extended is optional and yawning is always fun too,
What does this mean, it means relying on your technique.
1-Find contrasting colors, single spot metered with manual controls Focus on the edge of your subject/background, hold the shutter 1/2 way and re-compose, fire the frame
2-Focus on the eye-using your AF point directly over the subjects eye(rhinophores etc) the contrasting colors in the eye or the star around the eye should be enough. Even try using the Lure, often time that is enough as well
3-focus lock.There should be a thumb activated lever on the back of your housing that allows you to lock focus anytime without removing your eye from the viewfinder.
4-Switching the camera onto Manual focus-last resort option but effective as well. Behaves the same way as focus lock because, well it is locked. Adjust your focus by moving your camera back and forth.
Using the focus lock also allows you to fire your Ikleite strobes as fast as you can, 1/2 power means even dumps no problem
Hope this helps larry, good luck!

Slow responding to your help, great info with lots of things to try. I missed too many black frogs the last couple years cussing underwater at the camera and it was me all along !
Retired and diving the world
