There are a couple of other tricks, too, mostly from the wild-hair school of
portrait photography. I haven't tried them yet, but they involve odd blend
modes and such, but do a good job of hiding the kind of effects that a blue sky
might produce in the tops of trees and such. Mostly the tricks are used by
compositors in removing a subject from one background and placing it on another.

Yep. I hit some content-aware roadblocks, but by and large it's a real winner.
I find it especially useful when I've fixed perspective in a wide angle shot.
When then saved to a .psd file, the fixed distortion image has a nice gray area
where the vertical or horizontal fix has been made. The old way was to crop the
image, which meant you might as well have used that 35mm lens rather than the
24. With content aware, you use the magic want, select the gray, and
fill>content aware. There's usually a faint line where the filling occurred,
but that's an easy fix with the healing brush.

The last image was done this way. I used a 21mm lens, but had to tilt up
slightly to get all of the rainbow. Content-aware fill took care of the mess I
made when straightening the perspective. At least I think it did. Now that I've
focused Moosevision on it, I wonder. <g>
