de-fish-eye-ing a picture

I have a fish-eye style wide-angle lens, are there any free packages out there for correcting the distortion (I expect a little detail loss in the corrected areas) or am I going to have to dig out the old code books and write one?

there is a button to press in paintshop pro that does it but you have to pay for PSP

You get a free 10 image trial with PTLens[/url]

Oooh I never knew that about PSP, I have that free with work (and I dont have any dodgy copies at home at all!). I’ll hunt it down, thanks.

If I cant find it I’ll find PTLens and reverse engineer it 😀

Also if you use Nero for CD burning then some versions come with Nero Photosnap, which has a really simple function called “Lens distort” in which you can “pin cushion” the image, this reduces/removes the barrel effect caused by the fisheye

PSP / Photoshop correction is for barrel distortion from cheap wide angle lenses isn’t it, will it work on a fish eye lens? a proper fisheye has really pronounced distortion so may be better off just using a non fish eye lens?
