EIR film speed with filters...

I was responding 100% to the OP as well...if it makes a difference.

At least I learned the word "grok" from this thread!

Possibly the most important, most "Heinlein" thing you've learned today ?

EIR 120

That film looks awesome. So it was a unique product which has been pulled? Lovely...

I don't think anyone has commented on the availability of EIR in 120, converted from the 9.5" aerial format.

When you refer to a #12 filter, it's a Wratten reference number and is just a bit deeper than a #11 which is your "standard" K2. There's a great deal of information on the filters under Kodak Wratten on Google
I believe coirehogan refers to CC50Y when talking about CC filters.
