Scanners and Scanning

My portable scanner went phooey on me Wednesday and decided to quit working. Guess it thought it should be able to retire too! So, I spent yesterday afternoon shopping for a scanner. I had received a 'Best Buy' gift card from some of the folks at work so went to the Fort Wayne North store first. Well, it turns out they have stopped selling 'stand-alone' scanners. All they have is the 3-in-1 kind (printer, fax, scanner combo). Not what I want. I want something small enough to easily take off-site, like to my Mom's or on research trips. The techie said the Jefferson Point store might have them though. Nope.

Went across the highway to Staples. They had three models in the store - small, medium, and large. The small one was just what I wanted. It's a "Canon LIDE 70" model and scans up to 8.5" x 11.7" originals. What's nice is that it doesn't need an external power source and it is small enough (1.5" thick, 10.25" wide, 11.75" long) to take on research trips...

I Spent about 4 hours this afternoon scanning letters and it seems to be working quite well. In fact, I think I like it better than the big HP model I have that cost a "lot" more than this new little puppy. The HP can do legal size documents, which does come in handy sometimes, but it's not exactly what I'd call portable.

When you scan documents and pictures do you attempt to "correct" them (contrast, color, etc.) as you scan them? Or, do you simply scan at the defaults and make any corrections later?
