Best Resolution for Scanning Photos?

Now that I’ve got my Flickr account set up and my new printer/scanner set up, I’ve got photos on the brain. Photos, photos, photos!

What I’m wondering, what I’ve been wondering for quite some time is: What’s the best resolution to scan photos at? Back in the day, when I was the production editor for the Bradford ReView, you scanned everything at 300 DPI and that was that. 300 DPI was about as good as you needed anything and when you printed it, it came out swimmingly.

But it’s been years since I scanned photos on any serious level, and I’m sure things have changed. I’ve got a better scanner now, and a better printer, and I’m not sure what to do.

I stumbled across this site, read it, and couldn’t make heads or tails of it. My head actually hurt about three pages in, and I still found myself no closer to an answer.

All I’m certain of is that the resolution you scan stuff in at appears to be only one part of the equation. The other part, I guess, is how big you scan things in. The guy from ScanTips.com has all sorts of calculators and things to help make things easier, but I can’t figure them out. I think I’m just getting stupider and stupider as I get older.

Anyone have any tips? Stephanie and I are planning to digitize quite a few of our photos, and we’d like to get started soon. Any advice you could give would be much appreciated.
