Digital BW, The Print

Thanks to all those who posted answers.

I thought about using a digital camera to proof but the focal lengths 
are so different between the digital camera and the camera I be using 
that I didn't think it would be suitable. Also, the digital camera I 
have doesn't allow full control of the aperture and shutter speed so I 
don't think that is an option for me.

 From your answers it seems that a little experiential judgment (and the 
correct EI) is required if I'm going to use T55 positives to proof 
lighting setups for portraits when the final image will be made on a 
silver negative -- or choose another polaroid film where the positive's 
contrast range is closer to that of the negative film.

Thanks again.
