Beautiful..... Antelope Canyon is my favorite place in the entire world, bar none.
Blah.... I'm usually not a shameless self promoter but you should check out some of the stuff I took there.
This is excellent though, the detail and exposure is superb. And you seem to have gotten a more subtle hold on the colors than I have seen before. Was it cloudy out? I'm just wondering what caused the blue cast on some of the rock.
