Neopan 400 at an E.I. of 100

[SamWeiss]

Has anyone used (the current version of) Neopan 400 with an exposure index of 100?

In looking at the Fujifilm data sheets (which themselves are hard to find - found in Japanese, and at the UK site) the lowest EI Fujifilm has on their charts is 250. The MDC doesn't go down to EI 100, too.

So, anyone with some recommendations on using D76 for this (all I have.)

Using the Fuji CI table (EI 100 is normally about CI 52, while EI 400 is CI 58) SO maybe D-76 for 7' instead of 7 3/4'.

I drew in the red lines to find CI 50.

This chart is at the end of the Neopan document,
and IS at the USA site. Good luck.

Thank you for the quick reply.

The table in the Fujifilm PDF indicates 7.5" for D76 (20C, 135 size) and not 7.75" you derived from the graph; from this could we conclude that Fujifilm prefers not the CI of 58 for an EI of 400, but rather something just a tad bit less? If so, I wonder how this would change the desired CI of EI 100? Since we are talking of a difference of only 15 seconds or so, perhaps it would not be worth worrying about.

Also in the table, the recommended time (D76) for an EI of 250 is already down to 6.5" for a stock solution.

In looking over the Neopan 400 data one strange thing that sticks out is the notable difference in times between D76 and ID-11. E.g. a whole minute difference at EI 1600. Since so often one hears of the similarities between the two developers I had expected the recommended times to be pretty close.

It's an illusion to regard the film speed with great precision when metering accuracy and techniques vary so much (and scenes too, of course). When using Neopan400 I set my meter on 200, then for some scenes meter in such a way that the exposure would be the same as someone else with their meter set on 100 and pointing their meter slightly differently.

Yep. If this is an emergency, better to go with the chart. If you're doing a lot of it, test it.

ID:11 and D76 times always seem to be slightly at odds. Strange for what is supposed to be the same thing. I guess Kodak times are usually on the long side for most people and I usually end up developing about 20% less.
