longitudinal chromatic aberration - unable to correct using Color Editor / "create masked layer from selection"
Hi all!
I'm actually using 22 (and I'm having quite a few issues with it) but have a question that I'm hoping someone can answer.
I have lens that (when shot wide open) has huge amounts of purple and green fringing. Purple is easy, green not so much. So I go into the advanced color editor, pick the green color, and click "create masked layer from selection". Of course, I have to select the color again and then I'm able to take the saturation of the green fringing down as expected. But: if I erase part of the mask to not affect foliage, for example, the saturation slider will still affect the entire image.
Granted, I can create a filled adjustment layer, erase part of the mask, and then go through the color-pick procedure....it will work that way. But what good is "create masked layer from selection" if I can only affect the entire image? Maybe I'm not understanding something here...
Thanks!
Bernie

You have not mentioned whether the lens correction tool adjustments are of any value to the correction you need. I would start there whenever possible. Have you already used them when you try the Layer based correction?
Other than that, have you clicked on the "View selected colour range" option when selecting your target green colour?
Is it still ticked when changing the Saturation? If so, untick it. Does that help?

I think SFA is on the right track, "View selected colour range" option shows the selected color of the color editor in the whole image, disregarding the mask.
What I do in this case is pretty much identical to what you do, advanced color editor, pick the green color, then check the selected color range, then click "create masked layer from selection" and use either global saturation (if the mask is correct) or again redo the advanced color editor selection and reduce the saturation (maybe adjust lightnesss) in the editor.

Hi guys,
No - the lens correction tool is not enough. I played around with it again...and yes, "view selected color range" has to be unchecked. Thanks SFA! It seems like adjusting the global saturation as BeO suggested is better than trying to do it in the advanced color editor tool. I wish there was a way to create the masked layer and apply the SAME color again without having to use the dropper (since I have to zoom in quite a bit, I get a different range every time I click).
I can't believe that Capture One still doesn't have a tool to get rid of both purple and green fringing at the same time.
Thanks for helping out -- appreciate it.

Bernie,
If you have selected a mask based on specific colours selection at the source image level you don't have to be so precise with any colour selections for that layer. You can just de-saturate and get the result you want.
If your selection was less precise - perhaps because the are multiple slightly different adjustment required in more or less the same area/same mask, then you may need to repeat the colour selection but not for masking purposes.
Many of the adjustment possibilities in C1 can be applied in several different ways for different specific purposes. Sometimes it can be a little challenging to keep it all in mind at the time. Also very rewarding when one finds multiple possibilities using the same approaches and masking options.

SFA - good point. It's a learning curve. I'll keep at it.
Jernigan Lewis - well, one of my favorite lenses happens to be the AF DC-NIKKOR 135mm f/2D, which is well-known for both purple as well as green fringing when shot wide open (which of course is where I like to use it at lol). I know it would be best to avoid CA in the first place, but I still would like to know how to fix it should it occur...and that seems to be a tad more complicated in Capture One compared to Lightroom (which is not an option for me any longer, since I don't want to be without the layers and the subsequent control Capture One offers)
Thanks!
