I camera scan on a copy stand and I'm interested in doing more wet scanning. I'm just curious about something. Typically you use mylar so that the film can be held flat and moved around, put in a drum, you folks know...

What if I made a small tray with a diffuse bottom (or clear I suppose), and watertight edges and filled it with scanning liquid. Putting flatness aside for the moment, do I need the mylar at all in that situation? I'm sort of guessing that simply immersing the film in the liquid would present the same benefits without the waste...

Thoughts?
