>>2841782No, Neofin is also called Tetanal Blau/Blue, also called Beutler Developer.
Its an old one-shot developer designed for extracting long tonal range from slow film.
It is excellent for things like Rollei Ortho 25.
It is awful for Tri-X, but you get 2 films per vial, and I only had one ortho to do, so I threw a Tri-X in there just for fun. With a 20 minute dev time the negs still came out quite thin, and with massive grain.
