I am copying them using my digital camera but, as every slide I have copied so far has shown some CA somewhere, I am not convinced that CA was in the slide. So yes, the culprit must be in the hardware. A point of interest - when the slide is rephotographed it is in the original cardboard or plastic holder. The images include a small amount of the frame which has a beautiful fringe all the way round on the inside shading from green through to violet. _______________________________________________ Gimp-user mailing list [email protected] https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
