I find RC glossy scans better than anything else I've tried.
Matte surface will scan "fuzzy" because of light scattering on the surface. Size wise, I always scan film OR 8x10 thinking better details are available this way.
Can we please stop arguing/discussing suitability of scanning post on APUG? Mod has said over and over, for purpose of posting it on APUG gallery is suitable. On the same token, I'd imagine scanning for the purpose of APUG BOOK is also suitable. If anyone thinks it's not, please just report it rather than discussing it in the thread. (oh, oh.... I discussed it here too....)
