So like the title says i want to scan the labels on the dvd's i own but i was wondering how u guys crop a circle? i know maybe a dumb question but i dont know too much about editing pictures. So any help would be appreciate it.

Thanks again

I know how to crop a circle in Photoshop............Choose the elliptical marquee tool,hold down the Shift key while dragging out a circle,then Edit>>Cut.

yep thats how I would do it. If that seems a little too sloppy, you can create a circular selection and then transform the selection (Selection/transform selection) This will give a bit more control over you selection area so that ou can refine it down to a pixel.
