Thanks for the feedback and alternative suggestions folks. I have added a postscript to the original article which deals with how to overcome the issue of desaturating areas which you don't want to be desaturated.
It's good to see other suggestions coming through as well. I'm learning new stuff too ![]() Frank |

Go to the Chromatic Aberrations removal tool, move the sliders as you wish, and that's it. |

A rather late addition to this thread, but saw the link from the discussion of purple fringing.
This is almost identical to the way that I would remove fringing, but I would normally lasso the effected area before adding the hue/saturation layer which then fills in the mask for you. You can then always paint in other areas that you also want corrected. And used to use the same method with paint shop pro too, the only real difference being that they have a colour wheel, but you can still adjust the colour ranges by dragging the marked boundaries on the wheel. Shoving the saturation up to 100% initially can help whilst adjusting the colour range as it then more clearly shows which bits of the image will be affected. And I do find that sometimes I will decrease the brightness instead of increasing it, it all depends on the background - with a lattice of purple tree branches being an example. And it gets a little more tricky when the surrounding details aren't black/white; maybe green bokeh fringing on leaves or skin against a bright sky for instance: Desaturating the purple then gives people a grey edge which is no better, so from within the same tool/dialgoue, by adjusting the hue slider instead you can essentially make the purples into reds. It's rarely a perfect solution, and a small adjustment often gives the best results, just toning down the purple, but enough to say that it's less prominent particularly when viewed from a sensible distance.

I use about the same method as Frankman does, but simply use a duplicate layer in Photoshop, select the bottom layer to make the adjustments, then select the top layer and use a soft eraser- brush to bring out the portions treated for CA while leaving everything else intact.

Awesome tips! The prevalence of CA has actually made my shy away from bird shots, as I've found it worst on dark birds against a bright sky. With this knowledge in hand, I might go back out and try to find some birds and get some good shots!
Thanks! |
