Excellent results. It wold be interesting to compare a transformed
fisheye pic to a corrected pic from a rectilinear lens of equal focal
length.

I was amazed to see how well perspective errors can be handled with
simple PhotoShop operations. I only tried them after reading your
comments here. What a joy it was to see for myself how simple and
intuitive these tools are.
There are a lot of options for remapping images now each with ever
increasing
scope. I primarily use a free-ware application called Hugin to
implement all my
distortion transformations now, it's extremely accurate and very
flexible (much
more so than PS and you know how well that works).
Just to cite an example when the link for the new fisheye zoom demo
pics was
posted a week or so ago I transformed some of the images to see how
well they
might work for me, see the following links (btw these are not my
images so
apologize to the author). The image bellow was transformed in a single
transformation which took only a matter of seconds after some critical
control
points were selected. Both images have been reduced in size by half
and the
original image was also converted from Adobe RGB to sRGB color space:

Granted it's an extreme example but it's a good one none the less, I'm
betting
that I would have been able to do a much better job had I been able to
work
directly with the RAW file too :-)
