Re: What if you want a chemical b&w print from your digital data

[Godfrey DiGiorgi]

It's one way to do it. Someone has designed a digital enlarger to do 
that type of optical projection, streamlines the process quite a bit as 
projector optics are not designed for near-field imaging normally.

Another way is to use your printer to create digital contact negatives, 
suitable for printing onto silver-halide paper. I worked with this 
concept a little bit when it first surfaced about 6-8 years ago; my 
friend in San Luis Obispo produced some stunning 11x14 prints with it 
too. This is a wonderful process ... a little time consuming, but 
allows you to make negatives which are accurate and calibrated for 
easy, repeatable printing.

See Dan Burkholder's book, "Making Digital Negatives for Contact 
Printing" ...
