Carwash Cave Entrance, Mexico

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!

You're lucky to have got away with the rear diving pointing their primary at the camera, given the shutter speed that must have been required to capture the ambient light.

Thanks for your comments. I "got away with" the rear diver pointing their light at me by using a shutter speed of 1/60th. I was able to use that fast a shutter speed because I increased the ISO (I shot that image at ISO 800) enough to expose the cave opening.

No, I wasn't using a glass dome - I use Aquatica's 6" acrylic dome with a Tokina 10-17.
