You can hold your camera in your lap as you do a back roll or have it handed to you after you are in the water.
Because of the current and surge you do a back roll and kick hard to get down to 60-80 feet where you hold onto a boulder so you are not swept away. You need to stay with your group and not be separated from them to prevent yourself from getting lost forever.
I took my dslr rig on one dive at Wolf and that was enough, I needed two hands to hold on the rocks at Wolf and Darwin.
