Jill Morgan Posted August 10, 2014 Share Posted August 10, 2014 I am noticing that over the past couple of months, almost all my shots that have been taken in late afternoon have green CA. As fixing the CA does affect the detail, is there a filter that I can buy that helps with this at all? Mid-day shots or indoor don't seem to have this issue.

Bill Brooks Posted August 10, 2014 Share Posted August 10, 2014 Light later in the day has a higher green component so green CA is more obvious. The simple but expensive solution is to use a higher quality lens. Link to comment Share on other sites More sharing options...
Jill Morgan Posted August 10, 2014 Author Share Posted August 10, 2014 Since new lenses are not in my budget (sure wish they were) I'll have to cope with it I guess. Or try to get out mid-day for shooting instead of late afternoon, early evening. Yet I love the effect of the sun lower in the sky. Jill Link to comment Share on other sites More sharing options...
Allan Bell Posted August 10, 2014 Share Posted August 10, 2014 Can be removed in image processing software, depending on the software you have. Allan Link to comment Share on other sites More sharing options...

spacecadet Posted August 10, 2014 Share Posted August 10, 2014 You may not want to take the risk, but I've only once had a fail on CA, and it was the really obvious dark edge against white sky kind. I use kit lenses. Link to comment Share on other sites More sharing options...

To my eye, it causes less image degradation than ACR and the CA removal is quite easy to do by just hitting the offending fringe with an eyedropper.

I've seen barely a trace of any kind of CA or purple fringing in my images since I started using this option, even with my budget lenses. Link to comment Share on other sites More sharing options...

Jill If it does, you'll probably have to shoot in JPEG mode, which I've started doing most of the time. This hasn't been a problem for me, though. The JPEGs produced by today's cameras tend to be very good indeed. Link to comment Share on other sites More sharing options...

This hasn't been a problem for me, though. The JPEGs produced by today's cameras tend to be very good indeed. Depends on the camera. My Lumix G5 can produce corrected jpgs (for distortion and CA), but ACR and LR also automatically apply the necessary corrections by using parameters (separate radial distortion coefficients for R, G and B image planes depending on the lens and focal length in use) which the camera stores in the RAW files. Works very well. I very occasionally get some purple fringing around high contrast edges in the extreme corners, but the LR eyedropper sorts those out if needed.

So maybe when I go out next time I will shoot RAW and jpg instead of just RAW and compare. Jill Link to comment Share on other sites More sharing options...
Colin Woods Posted August 12, 2014 Share Posted August 12, 2014 You could also download a trial version of DxO Optics. I love it and it works a treat on CA of all forms. Col Link to comment Share on other sites More sharing options...
