I'm talking about the redish/purpleish line along high contrast boundaries such as bare tree limbs against a bright sky. Every other raw converter that I've used for the past 18 years refers to that as CA. Yes, it can be corrected in Studio if you turn off the auto profile and manually move the sliders, but...and this is a big BUT...you cannot have both CA correction and at the same timestrong text**** have other lens bugaboo correction such as lens distortion (which is provided by the profile.)
Most (all?) of the raw converters, except Studio, that I use nowadays that have incorporated lens profile correction allows for all the corrections provided by the profile AND a checkbox for CA which you can choose to turn on/off. If I see some CA in my image, I click that checkbox and...boom...CA gone!
The best I can do in Studio is to turn the lens profile on/off and see what changes it makes to the image. Then, I leave it off and manually move the sliders to correct for the distortion, CA, etc. I mean...it works....but, it's a kludge solution IMO.
