For reference, and if anybody wants to discuss. I'm including this information for P30 because Kodak does not list times for this recently released emulsion in their J-109.
I've made these exposures as carefully as I could and eliminated as many variables as I realistically could. While it is not scientific, and certainly not up to ISO or probably manufacturer standards, it is as accurate as I can make it with what I have available to me, and certainly accurate enough that I thought it...
At 11 min it appears way over developed. Gamma greater than 1. Maybe 5 minutes or a lower temp. I used to put ice in spare bottles to bring my Jobo down to 18C to process some high contrast film as continuous tone.
Also, if you have a darkroom, repeatable light source and incident meter, why not just sandwich the film with a stepwedge and avoid the lens altogether to make the H&D plot? Your H&D curve looks nice, but seems like it would be easier to make just a single exposure rather than a series.
Gamma is greater than 1, how would you ever print it? Development should not change the ISO speed. It just changes contrast. Jone's speed point, the tangent for '0.3 times the gradient,' moves to the LEFT (more sensitive) when development is less. This is very basic stuff.
The curve looks great. Have you tested P30 with D-23? I had great success over the weekend at 1+1. I posted some pictures in the Film Ferrania P30 thread. How do images look? Would love to see some that were developed in replenished Xtol.
Ouch!my lab was burglarized over this past weekend and all my stuff got stolen.
I’ve not done D-23. I’m working on getting some images in replenished XTOL, though it’s gonna be at least a few weeks as my lab was burglarized over this past weekend and all my stuff got stolen. It’s covered under my business insurance, so I’m fine, just have the annoyance and lost time to deal with.
Ouch!
Did they steal film development equipment???
This must mean that Film is not Dead!
Sorry to hear that! I know the feeling. Way back in 2005, I was out of country and came back to find my house had been broken into, and ALL my gear stolen, along with all electronic devices, clothes, jewelry... The bastards even broke into my darkroom, and stole my precious densitometre. Then the pukes used both my vehicles to transport everything! Thankfully they left my negatives intact. Insurance replaced all my stuff, but my wife lost very sentimental jewelry. NEVER want to go through that again!
thx. Yeah, not pleasant, but at least nobody was in the building at the time, so no injuries.
I'm assuming you have backups of anything digital that has value to you.
After that experience, we got a big dog, and an alarm system. Wish we had both to begin with! We were pretty sure who was responsible. There was a criminal living in the next neighbourhood. When he was released from detention, break ins began...houses, cars, etc. As soon as he was detained, the crime spree ended. Gets out again, and guess what happened? There hasn't been a crime spree for several years now so maybe they locked him up for good!
yeah, I’ll be looking to beef up some security measures, though I doubt it’ll be much of a deterrent. The police said that somebody has been systematically hitting all the buildings in that area over the last several months and they have a team assigned to the case as the accumulated loss between all the businesses hit so far has exceeded a million dollars in stolen currency and equipment.
