    PTLens, correct chromatic abberation, fisheye, ...

    I found this little application on the internet that can fix faults caused by a 'bad' lens.
    This little application can fix chromatic aberation, fisheye, distortion and vignetting (but don't expect miracles).
    It can take some time to get the correct settings, but when you have them, they work pretty well .
    10 images are free, a license costs $10 (or more if you like ).
    It's here you have to be: http://epaperpress.com/ptlens/

    2 examples:
    Canon Powershot S2 (only chromatic aberation)
    click here

    Panasonic FZ5 (distortion & vigneting)
    Before


    After (not yet perfect tough)

    Your first example photo was amazing, there was hardly any evidence of PF left in the edited version.

    I tried playing a bit with PTLens and the S3 purple fringing example photo from http://www.dpreview.com/reviews/canons3is/page5.asp but it didn't really work well. Or I managed to get the radioactive looking sh*t on the stones look more like a normal bird product ( ) but it severely mixed up the foliage area in the upper part of the photo. I think that it would be great to just select some areas where you want to apply the editing so that the rest of the photo stays as it is. Probably this can be done somehow with Photoshop and similar but those are all so complicated programs to use. And anyway I'm not going to spend any money on software. Gimp is free though...but at least as difficult to use as the others.

    There are lots of noise software around but not so much for these chromatic aberrations...

    It's indeed a photo that can't be filtered that much.
    If you realy want, you could cut several parts from the photo and fix them using several settings, but that would be a waste of time, don't you think ?
    Anyway, I've fixed several photos till now and it still works, maybe it's free anyway
