Where is the best place to find 35mm film and to get it developed?

But sometimes it's good to have it professionally done if you want the highest quality. Commercial drum scanners have the potential to produce incredible detail, better than even the best digital cameras.

The developing done by the mailers is good quality and generally fine for color slides and B&W. If you want very high quality prints made, then there's some professional film developers still out there, but they are quite expensive.
