MacOS. 10.15.7 Affinity Publisher 1.10.4 I am preparing a book of black and white photos to be printed in four color B/W. The picture files are RGB placed into my Affinity doc set up in cmyk. Images which I adjust (levels, brightness/contrast etc.) in Affinity Publisher all show a colour shift. Most of the time the shift is very subtle and barely noticeable in Publisher but when I export to PDF the shift becomes very obvious. The greater the adjustment, the greater the colour shift usually towards blue. I have used the same method to publish full colour images with adjustments giving no adverse effect. Is this a bug or am I doing something wrong? See the attached screengrab

Hi, I am new with Photo for Mac and need to adjust the colour balance differentially along an edge of a photo. It is a scan of a very old colour negative with substantial colour shifts close to the negative edges. I have looked into gradients, feathered regions, but neither seems to be either right or easy or I am not yet skilled enough. Can someone suggest an approach for tackling this? Thank you in advance for any advice. Ron
