The topic of slide and/or negative scanning comes up here periodically. There was a good discussion a few years ago - [webmasterworld.com...] - at which time slide scans were costing several dollars each (at least). Now I'm seeing prices for basic scans of well under $.50 each.
I'm sure many of us here spent part of our lives in the pre-digital camera world and have a collection of 35mm slides or negatives tucked away in a closet. I know that I have quite a few of both, and I think the time has come to digitize these.
So, for those of you who have been through this process, what do I need to look for in a service? These are mostly family and travel photos and the like - they aren't going to be used for magazine reproduction - but I don't want to end up with lousy scans, either.
It looks like most services offer common scan resolutions of 2000, 3000, and 4000 dpi. What with typical grain on 35mm film, is it even worth considering 4000 dpi?
The other variations are the level of image processing. At a minimum, most offer automated ICE dust and scratch removal and image rotation. Some offer more sophisticated automated and manual image corrections (for an additional price).
I'm looking at mass conversion - thousands of images - so I imagine I'm looking at a lower-end service. If I have any individual images that I want to publish, I'd probably re-scan them myself or use a higher end service. I just want to avoid looking at these a few years down the road and thinking I should have them all scanned again.
Any suggestions for the best way to shop for this kind of service, and what I should look for in terms of resolution and image tweaking? Any pitfalls to avoid?
