@Alex: hahaha, 
I thought you ment the reflecting disc on my girl's face. I already got some reactions that those masks are "not done" anymore.
I am thinking about joinig the competition next year, probably the Grevelingen one.
Kees, can you explain me a bit what is allowed on the processing side. can you use raw, or is it jpg only.
E.g. white balance: just the kelvin and hue settings, or can you use something like the colour wheel as well.
Contrast; just the contrast slider, or can you also use curves and levels. I asked the organiser a question about this once, and he said i could use that, unless i recieved a message back it was otherwise
Well, the reaction of the organisator is actually the truth. It really is no hard rule.
What I did:
I used RAW (ofcourse)
WB: only Kelvin and hue
contrast: only plain levels, no curves
sharpen: smartsharpen in PS
You probably get away with a lot more, but I didn't.
Just join the championship, not the Grevelingen-cup (It is for starters). You really will learn a lot, you have to shoot in 4 different categories and that is a whole different thing.
You have to make a good plan on forehand, scouting the divesites weeks before, planning the dives for tides and currents etc. etc. I did 6 dives over two days, where the shortest was 17 minutes for the macro (I knew where, what and how I wanted to shoot the picture). The longest was 55 minutes before I finally find a reasonable fish (that is the only categorie you can't plan).
