Filter/Speed/Meter

["R. C. Lacovara" <lacovara@xxxxxxxxxxx>]

Folks,

I see that you share exposure information by stating the filter which you 
use (often an 89B) and then the film speed. That seems reasonable. But 
sometimes it's not clear what you are using for a meter. I suppose that 
light meters are similar in the visible, but do they not differ somewhat in 
the IR?

In any event, could someone tell me, for either HIE or Maco, a 
filter/speed/lightmeter combination?

I have tried a Hoya R72 over my Weston III and IV, but despite several 
sources' claims that these meters are IR sensitive, this is hard to see. 
I'm trying to rig a better filter mount for one of my Westons.

Thanks,

Bob
