That tells more about you than about the posts you seem to be targeting.
But seriously, to answer your question: there is no science in amateur densitometry/sensitometry tests. It's a festival of spurious correlations, unaccounted-for covariation, and measurement+operator variance so big it can be seen by one those swarms of Elon Musk satellites.
None of this stuff would even remotely get through the editor of (let alone be considered for peer review by) the journal of South Surinamese and Peloponnesian Gender Studies.
You're saying you're getting out there and actually doing some photography with this film? Are you mad?

That tree image is great, Alex.My madness has been put in full display in the gallery for few days now.
That tree image is great, Alex.
Okay, to bring this thread back to its original topic (I apologize for my earlier departure), I have a first curve with, what seems to be, the right amount of exposure. The toe is what I intended, which means the first two steps of the step tablet are B+F density, and then it starts climbing. This was 8 minutes in D76 (Kodak) 1+1 at 20C in a rotary processor. This is just raw data, no analysis, yet. This is it from me for now. More, hopefully, next weekend.

Just a reminder Brian, if you don't like the technical testing, examples of your photos with the film are equally appreciated here. If you can, it would be nice to see some that aren't developed to the unusually high contrast that we have already seen. Some darkroom prints would be nice too.
It was for levity sake.
Well whoever complained really doesn’t understand research testing or deadlines. Sad… no, pathetically thin-skinned.
No worries, I deleted it.
I agree. It's got a great mood, a sense of mystery.
Some trivia here. X-Rite did make a serial to USB adapter for theDTP32 automatic reading densitometer. This is not the model I have, however, and I don't have this adapter.Fantastic. You are right. I just confirmed it by opening up the manual, which has been sitting on the shelf all along. So all I need is a RS-232 to serial cable plus a serial-to-USB adapter, yes? I owe you one. This is going to simplify things a lot. Thanks!
..my sensitometer, densitometer, and thermometer are calibrated and certified,.. There's one button, that's it. You put the film in and you push the button.
The best part of this thread is practically a peer review of aparat's results. Aparat is very open to suggestions and we are greatful for the efforts, time and expenses he/she puts in these experiments. I would have no hesitation accepting results of this quality for publication if I were a reviewer.None of this stuff would even remotely get through the editor of (let alone be considered for peer review by)
...we were looking for more information about the film, and somewhat surprisingly the supplier either didn't have it, or more likely, didn't wish to share it...
I looked back to see what equipment you are using, but in 2009 you posted you don't have a densitometer, so maybe you got your stuff recently? What are you using? New or refurbished?
Thanks for all the cool info you've been posting here! It's amazing how huge this industry once was, and how much great technology was available. To be honest, I don't even remember exactly when I bought mine, it's an X-Rite 810. I bought it refurbished, maybe around 2012-2014, from an authorized medical device dealer in the US. Fortunately, it came with all the paperwork and accessories, including the calibration plaque and film. I have since sent it out for maintenance twice. Sadly, it looks like these models aren't going to be serviced any more. However, the 301 still is being serviced, as far as I know, but it's unclear for how much longer.
tendency to have blocked highlights, at least in XTOL (stock). Might work a bit better in D-23.
Info is on the neg, though, so a little burning in the darkroom would fix it.
I'd guess cutting development by 10% would also be a step in the right direction -- and if you stick with Xtol, you don't give up 2/3 stop in the shadows.
If one wants to work with this film, one has to accept that sacrifices will have to be made. Question is which ones one is willing to make.
