...this is a terrific program...
Photoshop CS5 made a big splash with its Content Aware feature to remove unwanted items from photos, but I've found that InPaint is just as easy, just as effective in most instances, and infinitely less expensive (even when it's not on GAOTD).
Having now had some opportunity to play with InPaint
myself, I have to say that it seems like a classic example of a specialised/niche software tool - it really seems to do only one thing, and it seems to do it really well.
That "one thing" is a very common requirement - remove or repair/mend objects/blemishes in digital images.
For example, I have been looking for something like this for ages, to repair blemishes in old photos. There's a similar tool in Picasa, but it doesn't seem to work all that well as it is difficult to avoid having it leave residual "ghosty" image particles around the repaired areas.
