It's very easy to scan 35mm at 2040 ppi native (not downsampled) in an Imacon/ Hasselblad. Let's see if you can figure it out. If you'd operated the scanner even the most minimal amount you'd know how.

It is otherwise fundamentally clear you know very little about high end scanning or post-production of any sort at any level other than that of a consumer of the finished scan.

More importantly, was the person who had you scan those transparencies aware that you were not going to be scanning them yourself?
