Hello All,

I was wondering if anyone has any experience with programs that remove the "fisheye" effect of some wide angle shots, and if anyone has any recommendations. I have some pics whose perspective I would like to correct.

I use Pano tools, but it seems to only correct Barrell & pincushion distortion.

I'm also aware that there are programs that fix chromatic aberration, anyone familiar with any?

Thanks!

I use PS CS2 for all you mention including the CA removal, works great.
CA can be removed while importing the RAW straight away although my method is different.

I'll just import with as little manipulations as possible (I can do better in PS  Wink myself).
Then "select all" and go to "Filter", "Distort" and finally "Lens correction".
Now you can De-Fish with "Remove Distortion", "Vertical and Horizontal Perspective".
With "Fix Red/Cyan Fringe" and/or "Blue/Yellow Fringe" you can remove most CA.
As a bonus while you are here anyway you can fix Vignetting and Level the scenery.

When done don't forget to "Flatten" layers.

It always worked for me this way.
Latest examples both taken with a Sigma 15mm fisheye.

Hello Willem,

Nice shots there, and thanks for the advice!

I figured most of the corrections could be done with PS, however I still use PS 7.0 but will try these out as soon as I install CS2. My real intent is to correct some distortion on my old film shots (curved horizons, slanted buildings, etc.)

There is a canon lens of mine that has some CA - I think its the 16-35 - especially at the 16mm end.

Those options are'nt featured on PS7, the only thing that comes close is "spherize," but its more of a special effects thing.

BTW, how do you fix vignetting? Is it a CS2 feature?

Thanks again, your post was most comprehensive.

Piece of cake in PS2, same procedure.

Yes that's also a PS2 feature, infect all I mentioned in my previous post can be done with the same tool "Lens Correction".

Wow, PS 2 seems to be very complete, cant wait to try those features! I hope its not processor-hungry when it comes to RAW editing, I use C1 and it can be very processor-intensive.

thanks again
