Thanks you for your reply!
Yes I agree that sandwiching between glass is the most effective. My issue is that I’ve shoot quite a lot of film and I just simply lack the free time to be able to scan it all that slowly. I already struggle to find the time to scan with the carrier.
Unfortunately it seems my film is always wanting to curl, Both length wise and width wise. Not sure if it’s a development issue or manufacturing.
Even laying the film out flat on a table with heavy books on top for days at a time doesn’t seem to fix it.
The MK2 seems faster but like you say, a design which allows the ability to move the film seems unlikely to keep it flat. At least with the MK1 the film is indeed held in place and not allowed to move while the pressure plate is engaged. So thats why I’m skeptical of Negative Supply’s claims that the MK2 is an improvement in flatness.
