There was an article about the results from a Nikon 990 image being used on the side of a building in Time square <http://www.dpreview.com/news/0011/00110205coolpix990bigprint.asp> that shows what can be done with a small file and a decent viewing distance.
The rule of thumb that we use is that for a 48 sheet, we supply an A3 artwork (from an Imacon 3020, 4040 or Ixpress 328). There are stories about doing the same from 1ds, 14n or even S2 files. A drum scan from 5x4 should be equally capable. Just my thoughts..

The art of professional digital photography is to convince the customer to accept crap. If anyone might get within a hundred meters of the building, you need the highest practicable resolution, and this is the 88Mp, 250MB files produced by the 16 shot backs (that can do 22Mp in single shot). If you need panoramic format, you have to tile and stitch. Scanned film is not really practical, as most of the detail is grain - unless you are scanning ULF. If you do not have a 22Mp 16 shot back - beg, borrow hire or acquire one - let someone else have a go - convince them to accept what you can produce. =============================================================== GO TO http://www.prodig.org for ~ GUIDELINES ~ un/SUBSCRIBING ~ ITEMS for SALE
