So cool! I have never heard of that film. I use 669 and the negatives are dark and hard to see. Thanks for getting back to me. :)

^ Your welcome, type 51 was the rather less well known brother to type 55... with both these films you had a choice, expose for the print or for the neagative... with type 55 the difference was close, so if you played it right you could get a neg and a usable print... Type 51 is High Contrast, hence the HC in the name, the prints are outrageous high contrast, but the negs could have wonderful tonality if exposed correctly.... iso 640 for a print, iso 50 to 80 for the negative.... The pos/neg films were great, the negative was just washed in a simple chemical bath and hung up to dry, scanned wonderfully and made great darkroom prints too....

How do you scan a negative and make it positive?

^ Hi! Its uite easy really, many ways to do it, your scanner should have an option for scanning black and white neagtive film, if it does, then you are good to go, or you can scan it as positive film an invert it in photoshop,,, really no problem... remember this is a real negative, not like the paper negatives some polaroid films produce... but those can be inverted too in scanning... the advantage with the sadly discontinued negative films is that you can also make a real darkroom print from the negative... the quality is astounding to say the least.... I have made 40x50 cm prints that blow digital out of the water... and I use a 1DsmkIII every day in my studio....

g.
compared to other films, the red of the dress is quite light (or grey), no?
what was visible at the print? (or how where the negs of the 640 exposed pos? still trying to figure out what sense the different isos had... btw, they changed the 51 at a certain time. before, it was 320/50)

^ Hi G. There was virtually nothing on the print at iso 640... I could barely make out the deep black of the bellows and a faint outline of the tripod... other than that, pure white.... Funnily enough the negs of the shots I exposed at iso 640 are quite usable and scan very well.... I would say that the red of the dress is quite close to a panchromatic black and white film... maybe just a bit darker.. the skin tones seem a bit darker too.....
