But this jogs my memory, since Ron you are a member of the dye transfer forum too, and have the
necessary background in film science. And here the holy grail of matrice film per se would be something with a straighter toe and better highlight control, which has always been a shortcoming
of the process. I'm going to mess with developer tweaks to do this, and still have a lot of Tech Pan
8x10 on hand if old school highlight masking is still required. But rethinking the matrix film itself might
be in order. Jim's formula and Efke etc is pretty much a replication of traditional Kodak film.
