[Frameworks] Increasing Contrast

[Sam Wells]

Why underexpose, just push it. You should be able to push PlusX or
DoubleX two stops. DX will get pretty grainy, but....

Beyond 2 stops, no gain really. Actually if the lab just takes it to
0.75 or 0.8 gamma (what they define as amount of pushing depends on
their 'normal' gamma eithe0.65 or 0.7) & you be cool.

If anything I'd lean on the neg a bit - not really far over  like you
can with color negative, just get a nice density.

Shoot contrasty subject !
