Disable CA and purple fringing is impossible?
I had this problem in v9 and it's he same situation with v10... I never got any suggestions. Anyone?!
My original post...
It seems that regardless of whether you check the CA correction in the lens profile or not, it still removes CA.
This is normally fine, except I have some firework shots where all the colour is being stripped out due to C1P CA correction and I can't seem to find a way to disable it.
How can I tell C1P to leave my Sony RAW photos untouched in this dept?!

I saw your post earlier today day in the v9 forum, and said this. Does it help? I would certainly have expected unchecking the CA box to do it. And you can obviously have the Purple Fringing slider turned down to zero. You generally find that you only see the true effects of the CA and Purple Fringing controls if you look at the image ay 100% and you may need to do that to check what is really happening.
Also you could try changing the profile on the lens tab from Manufacturer Profile or whatever it says to generic.
Finally, are you sure that it is C1 that is doing this, and not something that is being applied in-camera?

So today, I went out and shot a crude target which is designed to show significant LoCA with my Sony FE 55, and indeed, the Sony JPEG images, show a disturbing amount of green and purple fringing. However, loading the images into C1P 10 nearly eliminate all of it. I've included both JPEGs and 100% crop screen shots of both to compare. The problem is, there is nothing I can do to turn this off in C1. Changing lens profiles or disabling CA correction has no effect. The purple fringing control also has no effect. It's like this LoCA reduction is burned into the RAW converter. Normally this is ok, but if you have a situation where you're shooting fireworks with magenta or green in them, or other situations where reducing purple/green is counter-productive, there appears to be no way to over-ride what C1 is doing.

I would like a way to disable CA correction.0 -
BTW, I've posted the RAW file to Dropbox if someone would be kind enough to confirm the results...

The original JPEG can be downloaded from Flickr using the link above to compare.0 -
I can't get at your file in dropbox - I get an error message saying your account's links have been generating to much traffic and have been temporarily disabled.
But I have been looking again at an image I took a few days ago. It's a raw file from a Sony RX10 M3 and includes a structure seen against a grey sky. If I look at the image at 100% and check and uncheck the Chromatic Aberration box, I see a distinct change at the edges of the structure. (The CA control is doing a good job, it seems.) The Purple Fringing control is set to zero, and I am not seeing any discernible change in this image if I change that.
If you are not seeing a change when you check and uncheck the CA box, I suggest you raise a support case.

Thanks. I'll try to get the file hosted somewhere you can grab it tomorrow. Would really like to hear what you see from the same image. Just in case I'm missing something.
I definitely see no change checking or unchecking the CA box or changing lens profiles and doing the same. Bizarre.0 -

Hey Ian, try this link to grab the RAW file... https://1drv.ms/u/s!AuEKhWpyVlFdgypqt7hc3b3qebF-

I tested it on my 10.0.2
The CA on or off do barely change anything but if you pixel peep you can see the difference under the window on the right. But I would not call it CA correction.
The Defringe do make a lot of change for the better but only in some directions on the paper.
It does not remove the CA all together.0 -
I don't know what to suggest. I agree that with your image I see no significant difference whether I turn the CA off or on.
On the other hand, here is an image of mine.
If you zoom to 100% and look at say the heron's head, I think you see quite a marked change when you turn CA on and off, or at least I do. Do you see that too?

Thanks. I could see a small difference with your RAW file so. It must be something to do with the a7RII RAW files or the particular lens profile. I've submitted a ticket to support. I'll report back here if anything comes of it.0
