I don't know what "locked beam scanning" means, I've only seen the term in Real World Photoshop and nowhere else, and it isn't defined there. An experienced operator may be able to tell you. >Also, is the film type (Velvia, Kodachrome) important? Again, I got different >answers from the bureaus.

Yes it's important, but the film terms are generic, one for all Kodachrome, one for all E-6, one for all negative. Kodak upgraded the dynamic range characteristics of the Pro scanner a few years ago, and the new transparency terms are identified with the numbers 4050. The negative film terms may not have changed, as they aren't ID'd with the new number. Anyway, I've scanned Fujichromes, Ektachromes, and Kodachromes and the generic 4050 terms work quite well, especially with no SBA applied. Sure, you'll need to tweak a bit in Photoshop, but what else is new? I find scanning negatives more problematic with this system, probably having to do with the lack of a reference for the operator.
