Thanks for all of the advice. I think I'll see what the auto swap partition size is with 1G RAM, then maybe double it. The reason I want to have lots of memory available is, I have a Bronica SQ-B camera, which produces 6cm square images on 120 roll film. When I scan these on my Epson Perfection 2450 Photo, I can end up with a digitised image which is 5100 pixels square. Amongst other things, I want to start using the digital equivalent of the graduated neutral density filter using two differently exposed images of the same scene, which needs much more than the 3x128M RAM and Celeron 633 I've currently got. And with a 3GHz P4 it should be much faster calculating the dithering for doing prints. Dave Fletcher
