I have Photoshop CS6 with Camera Raw 7.1 on Windows 7. However it seems that my CR is different from what I usually see. For example in the ''Lens Correction'' tab you are supposed to have only 2 tabs: Profile and Manual. However I have 3: the last 2 + Color. Also I don't have the ''remove chromatic aberration'' checkbox.
I am at a total loss...
No, there's 3 tabs in the latest version: Profile, Color, and Manual.
The Remove Chromatic Aberration checkbox should be at the top of the Color tab.
Chromatic Aberration in handled separately to Lens Correction profiles since 6.7.
7.1 introduces Defringe sliders in the new Color tab, and the CA checkbox was moved here too.
I don't have a Color tab and I don't have the old remove chromatic aberration sliders in Camera Raw Lens Correction tab. They seem to be gone completely. I'm having to open images in an old version of Camera Raw to work on Chromatic Aberration. How can I get full functionality?
ACR 7.2 is the current release version of ACR and ACR 7.3 is in beta, now.
There should be a color tab with color fringing, but there won’t be CA sliders, only an Auto-CA on/off checkbox.
Ryenke, what you are calling "full functionality" was replaced by an automatic sheme that's enabled by a single checkbox.
When it works, it's very, VERY good.
When it fails to detect the CA automatically - which has shown to occur with certain egregiously fringed images - then you no longer have a manual backup.
There have been requests to return the functionality, and so far those requests have been either ignored or it has been suggested to try to work around the problem other ways (e.g., by using the newer color fringing controls, which don't directly address the issue).
