Is there an easy route to take to remove small traces of CA in images in PS/Lightroom.
Also is there anything I can do when taking the shot to prevent CA occuring or is it something that just happens. I have a few shots that I can see it on, whilst other people cant see it. As I know its there I dont want it there.

All help - tips and tricks welcome.

Hey Stew,
Which lens are we talking about? LR3 has the C. abberation slider built into the Lens Correction set. Appears to work well for lenses that it has the data for.

Well well well if you shout loud enough Mr Lightroom appears. lol

Thanks for the answer Steve, it wasnt actually CA after all, it was some over sharpening artefacts. Theyre gone now, but thanks anyway. I must get myself some lightroom tuition. I keep finding myself pressing the PS icon instead of the LR3 on my desk top. Its a habit I need to get out of. I even got out my old underwater photoworkshop dvd to resolve the issue.

Cheers once again matey

I just used it today (probably for the 1st time!) on the edge of a manta, it doesn't get rid of it, it just matches the colour of the object, fairly easy....get Scott Kelby's book on LR thats all I've used..hell of a read tho!
