correcting purple fringing

[robirdman1]

Some scanned slides have purple fringing. Found a youtube video and it says to use the lens correction panel in camera raw.  In CR 12, I don't see such a panel.

you can do it in adobe lightroom.

for photoshop, Filter> Camera raw filter

Lightroom doesn't open on my computer. It says error reading catalog.  I never created one and after installing this is the message, so I've never used here.

In the Camera Raw Filter, look under Optics > Defringe. This works with the camera raw filter which I assume you are using as you mention that the slides are scanned rather than photographed.
