Hmmm Ron... you did crop out the butt... did you stick the infamous rod up the Rhino's butt to get that shot? KIDDING.
I always prefer about 10-20° off center from a head on view. You can see the insides of the mouth yet recognize it's a rhinopia,
This angle is the one then - just need the mouth open, never seem to be in the correct position when it happens or you are checking your air - been in scuba jail before by staying with a shark too long and missing one of the deco stops. 2 computers now one is attached to my camera.
I have a rod, I use it for keeping of the bottom in the muck - it doesn't go near anyones butt rhino.jpg 126.4K 169 downloads
