Subject: [Leica] grain in ilford/kodak/fuji B&W films at ISO3200

Hi,

I've been enjoying my M6, shooting at small poorly lit folk music
venues.

I don't do my own processing at the moment.

I've run three rolls of Delta 3200 through a lab that's processed them
in D76, 1:1 (I think), with good but grainy results.  Another roll of
Delta3200 that went through a different lab was less happy, I'm not
sure that they've ever seen the film before....

I'm curious about grain in high speed film:

  a) all other things equal, will a film (say, Delta3200) shot at 1600
     have less grain then when shot shot at 3200?

  b) given a particular film, can I control grain by specifying
     particular developers, dilutions, temps, etc???

  c) of the high speed B&W films (Ilford D3200, Kodak TMax3200, Fuji
     Neopan 1600), are there significant differences in their grain?
