I do most of my scanning on a imacon 848 that I rent locally. In most cases the 2040 max res for 4x5 is ok for the 24x30 prints. But I do have a couple of shots that I need to print larger than that. I remember reading on this forum of people scanning 4x5 negs as smaller formats and stitching. Anybody doing that? Details on best way to do it?
