Nope, it does not happen in Silverfast no matter if I scan in color or BW.
Turning off everything in the Filter tab reduces the amount of times that this happens, but it is rather inconsistent.
Now, I can see a certain logic in the greenish hue from the film, and as mentioned a certain color cast is fully acceptable, but the solarizing effect puzzles me.
@Krötenblender - my old version of Photoshop sometimes flips completely when presented with a 16-bit greyscale file, but setting to 24-bit color and BW negative seems to solve the problem. Just not used to this from Epson and Silverfast software.
Thanks for your help!
The stale vogue of drowning in technique and ignoring content adds to the pestilence and has become....part of today´s hysteria.
