Thanks for the tip on content aware fill. I'd not thought of that.
Often I get fairly clear sky that needs to be filled after perspective
correction and that's easily done with just a selection if it's not too
large an area. Use the rectangular marquee tool and make a long, narrow
selection of sky near the area that needs to be covered. Then use
edit->transform->distort and drag the edge of the selection box over the
area to be covered. If there's anything in there other than clear sky
it will get distorted but if it's just a small bit of cloud that may be OK.
