    Hi Monochromes,

    I've just bought (got :smile:) a pack of Orwo "Fototechnischer Film" FO65 (9x12, orthochromatic, expired in jan, 88. 50 sheets)
    I'm excited. I must try it, now.
    But.
    What is the sensitivity of it? (Yes, I know, that NP20 means 20DIN, but there's no 65DIN film in the world)
    How to develop it? In what? And how long?
    Heeelp, please... :smile:
    And thanks again,

    - L.

    ps: here's the complete list of all labels on the package:

    Good news--It's ortho film, so you can develop it under a red safelight. Try it in your favorite developer or something relatively standard like D-76 and cook until done. It's probably pretty slow, like ISO 25.

    All I could find that the number behind the FO relates to the contrast (1-6), with 6 being the highest. Develop 2-5 min in Orwo 71. No info about speed.
