I’ve been building my mirrorless scanning setup (https://www.parkermusselman.com/photo-negative-scanning) and have run into flatness issues with the DigitaLiza. After cutting 6x6 negatives into three frames, they do not reach the long ends of scanning mask. When the film is curled lengthwise (hotdog style) I get a TON of bow after inserting into the mask. Without ribs to hold the film flat, there is nothing to resist.
Has anyone experienced this? Do I need to move to another film scan? Thanks for any feedback!
