Film Speed for Kodak TMAX-400 8x10

[Jim Moore]

Another question before I take the 8x10 out tomorrow.

I haven't done any film speed test on the 8x10 TMAX-400.

I am thinking about rating it at 320 ASA.

Your advice is requested once again.

These negatives will be developed in XTOL 1:1 (or I could use TMAX Developer)

Thanks,

Jim

Pyrocat it and forget it ASA 320-400

Can you "Pyrocat" in a JOBO?

Where does one buy "Pyrocat"?

Is a frog's butt water proof?!@! Heck yeah!

Are you going to contact print on AZO? If so, I can forward you some times I got from Clay & Sandy, and the times I came up with after a little testing on my end.

A lot will depend on the contrast of the scenes you photograph. In general, high contrast scene= low film speed, low contrast scene= high film speed. Another important consideration is printing process. If you plan to print on Azo, it's higher DR requirements and associated extended film development effectively raises film speed. Developer and method of development also play an important part. Some developers won't deliver full emulsion speed, while others will. Assuming your developer does, and you overexpose by 1/2 stop, that's no disaster. If your developer doesn't then you might be underexposing by up to 1/2 stop, which isn't a disaster either. Good luck.

Thanks for the info. I don't have any AZO (yet).

I have some "original" Zone VI Brilliant Grade #2 (White Box) that I was planning to use to contact print the negatives on.

I'll send you some to play with. PM me your address again, I'll send out tomorrow.

Thanks Brian, I would appreciate the times.

Don't have any AZO, but I would like to go this route with my 8x10 negatives eventually.

I guess I should just go ahead and get the stuff ordered!
