Are there any good photoshop people here? My scanner sucks bawls... I'm looking to clear up a pic. Here's a snapshot of it so you can see what the problem is:

Something sure is wrong. It looks like you scanned something out of a newspaper there and then scanned it at low dpi as well. You could probably edge enhance and blur the image but it'll still look somewhat cruddy.

Yep. It's next to impossible to clean up a pic with low DPI. If possible re-scan and set the DPI to around 600 or better. That gives you plenty to work with. When I scanned SB's graduation pics, I set them at 1200 DPI. Big file? You betcha! Worth the space? Without a doubt.

It was set at 200, so I upped it to 300, and it was a little better, but I think I'll definitely try it at 600.

1200... that's insane. lol

Yep, it was insane. 35 M for each picture. But I can blow that mother up to poster size if I want to with no discernable loss of resolution. I also saved them as TIF files instead of JPG.

Re-scan the photo at min- 300dpi.

As stated above raise the dpi to a minimum of 300

It also depends on the size of the original and the size you want to go to. If you're scanning a wallet sized and want to blow it up to an 8*10 go with a higher DPI setting. If you're going to keep it about the same size or smaller, 300 DPI will be sufficient and keep the image size down. And if you're going to be doing any manipulation of the pic (editing, cleaning up artifacts, red eye correction, etc) save it to a format other than JPG at least until all the editing is done.

just a hunch, but if ya up the scanner resolution to...oh I'd say about 300 or so dpi maybe even as high as 600 or 1200 if you want a large file, you would get a better scan without all the graininess.
