Hi All. What is the best (easiest) program for a Mac to remove the vignetting and magenta color casting that results when taking shots with the M9 and the new Voigtlander 15mm lens?

 

I already have CS4 and Lightroom 2.5.

 

Thanks.

also works with M9

 

In LR you can try just to reduce the magenta saturation to 0 (if there is no other magenta in the picture) - works in some pictures

Thanks. I'm going to have to buy a gray card and make a profile for Cornerfix as there does not seem to be a registry or download section anywhere that I can find to get already created profiles for lenses. This will do the trick though.

I just took a picture of a white wall (as my grey card is too small) and it worked. I think a profile created by somebody else is only second best choice because your lens might be different.
