How to clean up chromatic aberration in LR5

Is there a specific way to do it in LR. I click "remove chromatic aberration", but I don't see a difference. I see there is a little Doppler but how do you do it with that. I have the famous 85mm 1.8, which is known to be the worst for this.

Personally if you have a lot of the purple/green fringes I would try to avoid using the global corrections. The global correction is going to really mangle any areas in the image that are close in colour to the range selected if you need anything but the absolute minimal level.

I will sometimes use the eyedropper, it will turn purple or green to match which slider the colour under it matches. You can only use it when it is showing purple or green. It will then set the range sliders to suit, as well as apply the correct level. At this point I may either use a local brush with negative amount to remove the correction, if the image only contains a relatively small area of unwanted correction. Otherwise I set the amount back to zero, and then use the local brush with a positive setting to remove the fringes as required.

With the positive removal of fringing it may become necessary to adjust the levels sliders, there are two control points on each of the sliders, to adjust the range of colours affected. The local brush picks that info up from the global settings. It will probably be necessary to adjust the amount slider for the brush too. I usually start out with it at 100% while I am applying brush strokes, and then go in and adjust the amount slider afterwards for the correct amount. Essentially it just desaturates the image over those particular colour ranges. So it may take a couple of different loadings of brushes on different areas to get the best result. I sometimes find that I either have to apply the correction carefully, and mix in some blacks/whites/shadow/h​ighlight/exposure adjustment to match the tone of the surroundings. Or do the defringe with a wider brush, and do the corrections where necessary with a new brush.

I see by your profile that you have a 7D which I believe can do lens specific corrections for chromatic aberration "in camera". Have you enabled it to see if the correction is sufficient?

i will check tonight. I do have the 7D

I'm guessing your issue is with green/purple fringing. Does LR5 not have a separate correction for that? If not, there might be a preset/action somewhere or whatever the LR equivalent is. The de-fringing on ACR with CS6 usually does a good global job, especially if you tune the color.

OR

if it is a continuous issue and you don't want to upgrade (assuming the new LR has the same functionality as ACR did pre CC), the free software Gimp has free actions you can download for removing fringing. It will mean saving as a tiff from LR and then importing back in though.

EDIT, just read the other thread, I guess the defringe is having issues with your case. Maybe see if there is a youtube video showing the procedure?

DxO is probably the best CA removal app.
