Digital BW, The Print

Austin,

 

Thanks, I confess I am somewhat new to all this (digital) and I am trying to
figure out the best path to get the best B & W images using digital means.
Since joining the group last week, I am feeling somewhat overwhelmed at the
learning curve.

 

I have been trying to follow the "digital,film scanning comparisons" thread
as best I can as I get up to speed on all this before I make some decisions
on which way to approach all this. In the meantime, I will read all the
group archive articles and try to make sense of it all.

 

About 10 yrs ago I was doing a lot of MF & LF B&W work and would like to
explore the best ways and means to getting as close to what I am used to in
silver printing via digital. I slipped away from photography to pursue
"multimedia" and am now turning back to it.

 

Any starting points you (or anyone else) can recommend as I begin this
journey would be welcome. The extent of my digital involvement thus far has
been with a Nikon 950 and an Epson 1270 printer. But I have a lot of MF&LF
negs I'd like to work with going forward.

 

So any help is most welcome,

 

Regards,

Tony

Hi Tony,

Actually, I was talking about scanning using a ND filter over the CCD.
Typically, film scanners scan B&W film using RGB filters...

I believe the Nikon scanners try varying the light source for the three
different colors (RGB), and I guess if they wanted to, they could just scan
B&W using white light...if that's what you're getting at. I don't believe
they work that way now though...unfortunately.

It's the colored filters that make the CCD sensitive to a particular
spectral range, without a colored filter (or simply using a ND filter), it
is responsive to the entire spectral range it is sensitive to, which is far
wider than the RGB range.

Austin
