Antelope Canyon is one of Natures finest abstracts. You did a nice job with it.
I know that technically an abstract isn't a picture 'of' anything, but I was looking at this rock face in LR and noticed subtle colours in the stone, so I pushed Vibrance and Saturation both to 100...
Just don't tell us that it's a rock face and it makes a perfectly good abstract.
Intriguing. Looks like star trails, but I'm not so sure.
