Hi, Thanks for the response,I have tried your suggestion but still painfully slow and eventually seems to stop. My Mac is running the latest Big Sur update. It has a 3.3 GhzQuad core processor, 24gb 1600 MHZ DDR memory. I am trying to load 200 layers,align and stack. I can now load the layers but even after 5 hours the layers have not auto aligned.... I realise this amount of processing will be slow but this is dire. Regards Peter. -- *Peter*
Have you tried a smaller batch of trying to align 200 large camera image is a huge undertaken perhaps your are running out of machine resources. How long does 5 image take. Can Photoshop stack and align 5 of your 200 images?
