Digital BW, The Print

I guess, I'm looking for a bit of a survey. Digital?  Scanned film?
Scanned B&W, color or chromes? What film formats? What scanner?
What B&W conversion mechanism, where applicable.

What enlargements do folks usually aim to achieve from the different
image capture modus operandi. 

I know folks here aim for fine prints, so I'm curious about what's going
on prior to editting and printing the digital image.

Thanks much.

Scott
