ok, so I have been given a photo to edit for a website. We don't have the original but we have rights to use it. It's current size is only 100DPI with the width being 320. We need the width to go to 480 and I can't figure out how to do it and make it look good. I've tried many different sharpening tech. and different levels and such and just can't do it.
Any suggestions?
