Color fringing help

[Matt Glick]

After lightly editing this pic, I notice some purple color fringing in the bottom left corner as well as the bottom. Any tips on how to remove this or to reduce it? I have tried in LR with removing the Chromatic Aberration and messed around with the settings, but this is new to me. Thanks.

Settings:
ISO: 1000
F3.8
87 sec exposure

I don't see so much CA as I see color noise and hot pixels.....and a lot of it. I use Noiseware for that. Minute and half exposure time you'll have that. The hot pixels you may have to pick out individually.

Foe CA, make an adjustment layer, go to the area of greatest offense and enlarge the image to the point where the pixels are hitting you in the face. Take the eyedropper, sample the color of the CA of interest then with your slider desaturate it to the point where it blends in with the surrounding information.

Works for me.

LR can't do Adjustment layers. You need Photoshop to do that.

Using LR's Details panel you can reduce the Color Noise.

Thank you both. Is there any way to avoid this from happening in the future? Certain shots that I like doing require a minute or 2 minute exposure.
