Hi I'm trying to get my head around the pros and cons of scanning B&W film. Reading zone-system articles (e.g. this one http://dpanswers.com/content/tech_zonesystem.php) indicates that B&W neg film is able to reproduce a very high dynamic range, EV 14+, which is higher than most digital cameras (except artificiall HDR techniques) and much higher than colour slide (EV 5) and print film (EV 10). Thus the problem for scanning them is similar to that for printing them - how to get as much of this range as possible into the scan with a scanner having a more limited range (EV 10) Reading scanner articles about scanning B&W negs (e.g. this one http://robertdfeinman.com/tips/tip11.html ) says that the problem with scanning B&W negatives is their low density range (around 2) compared to colour slide film (around 3.5). My understanding is this equates to EV 6.5 for B&W neg and EV 12 for colour slide film. Thus the problem with scanning them is that the whole negative is scanned into a small subset of the scanner's density range. Does not compute. Can someone explain which is correct to my small brain please? Many thanks. Chris, UK.
