Just a thought
Most negs I have are 35mm. I'm still trying to nail down a problem with one or both of my grafmatics that's keeping me from really digging in and generating more 4x5s.

Care to outline what a contrast mask positive sandwich is? If there's a previous thread, just let me know and I'll search later and post a pointer to this thread.
