The way I have understood the Scanscience process is that film after wet mounting on a separate glass plate is placed upside down towards the scanner, to have no glass between scanner and the film. This is not the case with Betterscanning. Am I right?
Betterscanning uses the same process – film is on the underside of the mounting glass, so the film faces the scanner’s glass and optics.
This is the process for both wet mounting and dry mounting.
