[alt-photo] Re: Official press release about HP large formatnegatives

[G Schmitz]

  So why even bother with digital negatives Terry.  Some here have belly 
ached, over the years, about the failings of digital negatives with 
regard to density range (and the granularity of that range).  That's not 
even an issue with film.  Toss in masking and you've got total control, 
on film, of a nearly infinite continuous tone scale.  What am I missing 
here.  My initial and continued attraction to alt-photo is that I can do 
it myself.  If I use a digital printer, produced by a large corporation, 
who's getting it up the shorts?

These methods can produce fine gradations and ranges of tone that will exploit the full tonal potential of a platinum print, that is  from a negative with a tonal range of up to 2.4. See my articles in View Camera and AG  which demonstrate the tonal ranges for individual processes.
