We use Photoshop 6 and 7 here at the newspaper, G4 Macs (my wife just got a G6, I think it's a 6, with Photoshop 7 and it's real slick, she's a layout editor) and a nice Epson flatbed.
Love playing with the toys.
We get a lot of REALLY REALLY bad submitted photos that have to be run in the paper. I'll get handed something to "work your magic" on and when I'm done I usually tell the person who gave me the photo not to tell anyone I can do such things!!!
The worst stuff to scan are drivers license's, anything that's been through the wash, postage stamp size photos, and the dreaded, "dageurotype dartboard" which is usually an older, almost "antique" photo that's been exposed to light too much, folded and crinkled into one twentieth it's size, and used as a dartboard.
No s&&t.
I actualy got a photo like that, with small holes it in like someone had it taped to their dartboard. It was also ripped about half way through and had been wet at some point and faded and scratched and it wasn't a great photo to begin with, out of focus and poorly lit.
I have the raw scanned photo and the finished one in my portfolio some where.... =)
A lot of photos from the 60's and 70's have some pretty bad color problems going on, those are fun too...
There's all kinds of cool stuff you can do with Photoshop.
