Mark's close to right (correct) here. With Genuine Fractals, one can blow up
an image and it'll be interestingly substantial. If you have a file that is
20 megs or more, then it'll do an excellent job.
A friend who knows much more than I says phooey on it however . . and that
bi-cubic interpolation is just as good.
I did take a shot in my backyard and using GF blew it up to the equivalent
of 4 by 6 feet. It was shot w/my 4 year old 1.2 megapixel Olympus) and,
gosh, but it looked terrific. I mean, yes, you could see distortion, but,
overall, the result was literally fantastic.
The other major prob w/GF is that it is extremely slow when you open an
image to much larger (or even not so large) size. You really need a fast
computer to make programs of this ilk work efficiently.
