Ilford PanF+ 50 H+D Curve with Replenished XTOL for 15:00 at 24C in a JOBO

Adrian Bacon submitted a new resource:

Ilford PanF+ 50 H+D Curve with Replenished XTOL for 15:00 at 24C in a JOBO - A development time resource for replenished XTOL and Ilford PanF+ 50

For reference, and if anybody wants to discuss. I'm including these times for Ilford PanF+ 50 because Kodak's times listed in their J-109 appear to be far too short and generate very low contrast negatives.

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...

I’m guessing that you will cover high sensitive film too.... (your efforts are very appreciated thank you) .

yes, I’m looking at Tmax P3200 right now, and have Delta 3200 in the queue.

Why is your time so far off from the one Kodak recommends?

I’m not developing it to the same contrast.

Thanks. I've noticed Pan F has been pretty thin, so I was just curious. Your tests have been helpful, by the way.

thanks. I suspect Kodak’s listed time is the reason why so many people say that panf is 25 speed. It’s just not enough development time to get zone 5 up to even 0.70-0.75 at EI 50, much less 0.85. It really is 50 speed film, it just needs more time in the soup.
