Thanks. It wasn't cropped very heavily. I think the spot you refer to is a water stain on the lens, due to the rain which caused the rainbow. I'll try to clone it out tonight. --Garrett
Nice colors in the sky! Seems to be suffering a bit from being cropped heavily. I see a dust-speck in the sky just to the left of top middle bird - when it even shows at f/5.6 it is time to clean your sensor! --Olaf
