Digital BW, The Print

Ernst,
I was suprised to see your comment at the end regarding analog to digital... :-)...made me smile.. So your seeing possibility.. I've have been playing with this for some time (almost 2 years now)  and am now certain that real possibility is their.. even if one is after larger images  (within reason). 

The raw files when shot properly out of current DSLR's are much better then most would think when moving film to digital.. It's a tight process but the controls available to us now with current software and raw files in my opinion offer more flexibility & surpass most of the software were used to with our drum scanners.. Anyway, who know's where it'll go but I'm honestly embracing it.. ...I'm have been experimenting with 4 exposures on 6x7's and stitching .. it workaable.. but I'd rather use the drum scanner .... I am honestly after a quick quality process for 35mm that is my target and I'm serious about it....

  Then  theirs the 80MP Leaf / Mamiya back..  oh and one more and this one honestly should raise a few eyebrows.. Lets remember you can do what's called multishot with a digital rig.. Hasselblad has a 200MP multishot (6) rig .. their doing this with a 50MP sensor .. http://news.cnet.com/8301-30685_3-20066021-264.html  .. I think we can sort of see the future now ..It's just not affordable as yet for most of us.... :-)..

  Ben,

  Your print size is A3+, roughly 33x48 cm, lengthwise 45 cm will be 
  usable. My experience says that 450 PPI is the optimal resolution to 
  feed a printer, there is not much to gain beyond that considering inkjet 
  technology as it is today. Often half of that will still be satisfying 
  with the right upsampling tools. Over the length you need 8000 pixels, 
  on the width 5844 pixels. With borders for matte mounting on the print 
  you will need less pixels than that.

  A 6x7 measures 56x72 mm, the 72mm length can vary in practice depending 
  on the camera but I start from the Linhof ideal format. To get 8000 
  pixels over that length you need a scanner that resolves about 3000 PPI. 
  The Epsons in the V class can not do that but will do more than 2000 PPI 
  with proper methods. On the length you will get 5670 pixels, on the 
  width 4410 pixels. The dynamic range is usually sufficient for B&W 
  negatives, it is different for slides.

  Proper upsampling and sharpening tools will help.

  I would say get an Epson, possibly the V600 or a secondhand V700 and 
  build up experience. A good operator is worth a lot, both on an Epson 
  and on a drum scanner. If you can afford and maintain a secondhand drum 
  scanner later on then that is the way to go if you want to stay with 
  film. The Nikon MF scanners are no longer made and cost a lot secondhand 
  and in my personal opinion the Flextights are not better in their 
  performance while they are going at an even higher price new and secondhand.

  With a Nikon D800 camera and more like that to come the hybrid 
  analogue/digital route is questionable anyway.
