    Keith;

    I found a source easily available. I'm making a rounded octahedron, pretty monodisperse at about 1.0 microns. If I can, I'll send you some though.

    So you figured out how to make them lie flat? Sounds good.

    I have a bunch of this in my freezer and would agree, there really isn't anything else close. Microscopic grain and a contrast range that can sometimes make you wonder how you'll ever get it all in a print. It's perfect for Pt / Pd.

    This is difficult to work with in 4X5 though. It is 4 mil thickness and it's a p*i*t*a to load. A whole new personality on 5X7 though where it becomes very nice to use. The curl holds it flat against the back of the film holders. I have about 1500 feet upstairs in the freezer. My hedge against a filmless future.
