There's a lot to love about digital photos that remain digital. You can store hundreds of them on a single CD; you can send them anywhere on earth by email; and they won't wrinkle, curl, or yellow until your monitor does.
Sooner or later, though, most people want to get at least some of their photos on paper. You may want printouts to paste into your existing scrapbooks, to put in picture frames on the mantle, to use on homemade greeting cards, or to share with your Luddite friends who don't have computers.
