Frustrated with photoshop

[dan33]

I need help with photoshop, I am scanning b+w negs on a minolta dimage scanner resulting in around a 20meg file. I then open in photoshop cs2 and then i crop slightly, the crop takes a very long time and the image ends up being 1.5 to 1.8 gig?? What am I doing wrong??

Are you certain that you checked the resolution that Photoshop is set to when cropping your scan?

Use your scanner to scan the image
watch what resolution setting you have. Dont let it go too much past 100 dpi for an A4 scan.

If you scan as a B/W setting this will also reduce the file size.

When cropping in Photoshop again make sure that your width, height and resolution are of a managable proportion.
