I went to a slot canyon a week ago. I took about 100 photos, I've started going through them, here's a small selection.

It's quite a difficult shooting envorinment. The light areas near the sky are ahout 10 stops brighter than the dark sections near the floor.

This  is an abstraction rather than a scene. It's for the competiton entry.

This is one of the widest parts of the canyon.

I forgot to add the link to the main photo in my previous story, so here it is.
