I don't know of a scanner that has a scan area beyond 13x18. I have seen huge graphic arts scanners, but don't believe they are intended for continuos tone.Originally Posted by Sean
You might want to set up a copy area shot the prints with 4x5 and scan the 4x5 negs/tranies. If it is for the web this should be more than good enough.
Sorry, this is none too helpful.
