Digital BW, The Print

As I read this thread I cannot help but wonder if a dedicated b & w scanner
does exist somewhere, it would seem like a good fit for radiography (medical
& industrial)

 

I am also curious to know if I should buy a high quality scanner or jump to
fully digital. I have lots of MF black & white negs I'd like to digitize, so
I would like to know more about the quality of current MF scanners, what to
look for/avoid.

Agreed.  But you'll never get really good black and white from any RGB
imaging device.  The only way to get top quality black and white is with a
dedicated black and white imaging device.  A CCD could certainly do this,
but only if it were truly dedicated to the task, with no color filters, and
I don't see anyone producing that.

Similarly, you can't scan color film and convert it to B&W with results that
come anywhere near to true B&W film.
