[LargeFormat] Light meter recommendations

[Jim Hemenway]

Hi Les:

My APO-Ronar CL 420mm, mounted on a Copal 3 goes down to 128. I think
that the Kyvitar does also.

And thank you for reminding me, somewhere in the house I have a Minolta
III (f?) which I used as a flashmeter.  When I get home later today I'll
have to dig it out of the Novatron case.  Forgot all about it!  It at
least must go down to a smaller stop than the f32 on my Weston.

Does anyone know at what f stop that diffraction begins for the 11x14
format?  8x10?
