Not Telling
While I'm still very much learning how to make good images u/w, I find it most useful to pre-visualize an image (what I'm after and how would I go about getting it) before getting in the water - particularly given the number of distractions once I'm in the water! On a recent cave diving trip I managed to actually make the image I had in my mind before even getting on the plane. It really helped that I had two very capable and willing team-mates to help pull it off!
Cheers,
Lee
