Topic: correcting purple color cast in old Gevaert film slides when scanned

[dk]

I have a number of 40 year old Gevaert film slides, all of which have an overall purple color cast. There are not always white points or mid greys to use as a point of reference. I am looking for a procedure that I can repeat with each slide as all have the same problem. Any help much appreciated. I mostly use PSE 4 with the Curvemeister plugin. dk

If the purple cast is consistent throughout the image, an Lab curve where you move the magenta and blue ends of the a and b curves, respectively, may do the trick.  You may be able to use the same curve for all of them.  It's likely adjusting will be required, using your main curve as a starting point.

Perhaps you can upload one of the images for the rest of us to try our hand at.
