    I haven't printed yet, but the numbers are in... You can go shoot with this information...

    I'm going to recommend Dektol 1:9 for 5 minutes (4 - 6 minutes) for a "N" Normal (7 stops) scene.

    This should give about 0.45 Contrast Index (0.4 - 0.5 CI).

    Approximately good to fit Grade 4 paper on a Diffuse Enlarger (Grade 4 - Grade 3).

    I measured EI 80. But I will recommend underexposing by rating the film at EI 125. This will help "Zone V" approach 0.30 density (which is where LP Clerc says you will see the most graininess).

    If you rate the film at EI 80 then "Zone V" density is around 0.60 (not bad in itself just not the grainiest).

    Thanks Gerald, I was looking forward to more developer suggestions. I know Dektol isn't going to be the "worst".

    Yes it's fresh Tri-X. But I may have used the wrong calibration.

    Compared to TXP-320 in D-76 I have an upwards revision in EI: 125 and 200

    (My calibration scale is likely reading low 2/3 stop).

    Thank you Bill. I'll be trying this soon. I'm going to have to go shooting again and probably shoot two rolls of the same scene so I can try variety of development. (I'm going to cut the film in half so I have 4 strips)
    Develop, stop, fix.... wait.... where's my film?

    I am doing some of my own testing based on Bill's testing.

    Shot Tri-X at EI=400. I always shoot at ISO speed unless I have a specific reason not to...
    Dektol 1:9 70F 6 min....
    Over developed a bit and quite grainy. I LOVE IT....
    Seems a bit over developed.
    This is actually grainer than Delta 3200.

    Now doing the same with 5 min....
    Develop, stop, fix.... wait.... where's my film?
