Just thought of something that can be a factor - in most of those photo disks that come back with your prints, there are two sets of digital images. A lo resolution and a hi res set. Usually in different sub-directories. Be sure that the ones you are using are the hi res version. (The ones you sent me were possibly the low res ones - two were at 72dpi, one at 96.) I believe you may do better starting with the hi res version, doing any touch up and then resizing/ changing the dpi at the same time. If this makes sense.
