My M5s need red dots!
In the big developing chart we all know, the combination Arista II ISO 400 and Ilfosol 3 appears only showing 9 minutes for film exposed at ISO 320 (at 20º C/68º F), in Ilfosol 1:9.
I exposed mine at ISO 400. Should I soup my film for longer or less than 9 minutes?
IIRC, the only indication given for Arista II at ISO 400 is of 10.5 minutes at 24ºC, and I don't want to soup my film at that temperature.
So, do I develop it for 9.5 minutes or for 8.5? I'll appreciate an answer. I need to develop this soon. Thanks!

Well... I guess I'll try it at 9.5 minutes. Since I shot the film at 400 instead of 320, one could say that I "underexposed" it a bit, so it will need a little overdeveloping.
Must be that I'm one of the very few still using this film...

Yes, 9 1/2 - 10 minutes will be close to the interpolation of these developing times for E.I. 400 and 1+9 dilution.
Take care about that Ilfosol hence it is an Ascorbic Acid type film developer with a very short lifespan when opened the bottle (2-4 months).
When not good anymore you will end with a blanc film.

Thanks for the Ilfosol tip, Photohuis (nice handle!). However, from what I've read, this is a new formula that addresses the short life of the Ilfosol (it's actually called Ilfosol 3), and makes it fairly reliable (up to one year after opening). I'm glad I bought the small bottle...
Also, thanks for confirming my hunch. There's simply no information about Ilfosol 3 and a bunch of not very old emulsions... I'm stuck with this Arista II film because I bought a fairly large amount some time ago, and then never used it. But things could be worse. Have a nice day!

It's up to you, but a 1/3 of a stop isn't something that necessarily requires any development compensation. Considering that you are starting from zero, it's possible the stated time is already too long. I'd rather start with something that may be a little low in contrast and adjust the next time around, rather than potentially over doing it.

I guess it's time to experiment... Thanks, Erik!

In this case the compensating is less then 10% so it is just a minor correction. Yes, Ilfosol 3 is much better then the old Ilfosol S which sometimes was already dead in the bottle when starting to use it.
The problem with any Ascorbic Acid type developer is that the time from active to almost zero can be reached in a few weeks.

I'm going to try at 9 minutes, so as to get what I imagine will be low contrast. I can always increase the developing time... or just expose my remaining film at ISO 320... I have at least 25 more rolls of the stuff.

In the end, I ran the film for 9 minutes. The negs look OK, but I'll scan some to see how they turn out; at first sight, they look contrasty enough but... we'll see.
