Cheers for your comments, I know that this sport is not for all - that is one of the attractions of it. We cavers are a close knit community where we must have complete trust in your fellow cavers within the group. This is because we are all good at something like getting through small gaps, climbing, diving or using ropes. So whoever is the strongest always takes the lead at that particular obstacle and makes sure that everyone gets through.

As for lighting on this shot, my wife had to get through this gap about four times, because the lighting was a nightmare as the gap is so tight and the rock so shiny, I kept burning parts of the image out with the flash. In the end I had to point the flashgun in the opposite direction and bounce the light back. Being careful not to light up to much of the image.
