- It's called Minit Mask (or something like that).

- I bought one and didn't much care for it. The contrast reduction was
- not very much, and I found small pits in the glass that showed up out
- of focus in the print. The addition of another piece of glass in the
- enlargement path also reduced a bit of the "snap" in the final print.
-
- Now that I think about it, I should have returned it for a refund.
- Anybody want to buy one cheap? :-)
-
- After basketball season, I think I'll finally break down and learn
- how to make real silver masks. Perhaps they'll eventually get it right,
- but for now Minit Mask is a shortcut to nowhere.
