Wot's photoshop?
Seriously, I just pointed the camera. It wasn't very dark, 7pm last Sunday. but it just responded that way to the glare.
I almost put it in artistic/interpretative but then I thought that's not right when all I did was press the button.

Glad you liked the rock art. You can post it up if you like, you're more of an expert on that sort of thing I'm sure.
