i just could not open a thread in the hybrid-forum.
Anyway: thank you for the answers

The problem about scanning is that the results are pretty different from the lab-prints.
I got reults from different labs from nikon coolscans and imacons,too. They did "just" correct brightness,colors and contrast in scanning.
After i made light-jet prints and scanned them to get similair examples...it looked different :/
