    Hi there,
    I am about to start testing some film and developer combos that are not "recommended" and I can't seem to find info on. Which is fine by me, as I am trying to experiment to find something interesting...

    However, I was wondering how I should develop a system to test with? What time, agitation cycle, temp should I start with? Should I bracket my exposures, and would that help me figure out how to develop my next batch? Is there a standardized or tried and true system used to test film and developers?

    So, here's an example of a combo I would like to try:
    Tri-X with FX-1
    So far I have only found details on using FX-1 with Fortepan 200: ASA 250, Stock dilution, 18 mins, 20 degrees, agitate 10 secs per 2 mins.
    Should I just use this info as a starting point?

    For the basic tests read Ansel Adams' _The Negative_. There is an appendix that describes the film speed test and the development time test concisely.

    If you want to take the time to read and understand the BTZS testing method, this would be an ideal way to go about your testing. What you do is expose step tablets on the film and develop at different times. Whey you are done you have a collection of curves with allow you to choose your personal EI.
