The Zeiss CA's

Unread post by jbtaylor »

Maybe the wrong forum but I was wondering how one deals with those pesky CA's that the Zeiss lenses are famous for. Are there use tips or just PP tips?
Please advise.
Thanks.

You just use a program which adjusts for CA, like Lightroom, ACR or C1 Pro. CA in this context is simply a different physical pixel size for the R, G and B channels. The correction rescales each channel separately (or two layers at a time) to match their sizes. You can also do this with an automated Photoshop action, if you know the percentage CA and how to resize the R and B layers (normally leaving the G layer alone as the main reference).
