Thread: diy f-stop timer

    diy f-stop timer

    Hi All,

    since I tried large format and the Zone System, I definitely kept missing a darkroom timer adapted to my needs.

    Hence my decision to build my own and release all relevant info for anyone wanting to build one.





    Comments welcome

    Cheers

    Elia

    No sound... I was unaware of the copyright of my soundtrack....I had therefore to remove the sound.

    When possible (very busy these days), I will upload a video showing the test strip with a real demo of split grade printing with test strips and dodging burning sequences.

    Cheers

    So, if I'm at f2.93 and I want to add 1/4 stop exposure, I would...get my calculator. In which case it is easier to add 1/4 stop exposure to the base time in seconds (multiply by 1.18). Maybe I need to see the manual.

    Agreed
    I have enough trouble setting my DIY Gas Burst timer with 3 time variables and pressure. I REALLY need the manual for Elias' f=stop timer.
