Strange one this. A roll of Jessops KB21 ISO200 b&w neg, made in Yugoslavia. Expired Jul 93. So Expired film made in a country that ceased to exist around the same time. It's almost certainly the same film as Efke KB21, an ISO100 film, DIN21 being equivalent of ISO100. Still made in the same factory, now in Croatia. So if it's the same film, what kind of stunt are Jessops playing here? ISO what?? Anyway, it's so long expired, any manufacturers test data is best forgotten especially as KB21 is a 1950s film, so who knows what this will do. Anyway, I exposed it at EI 80 and did the stand development trick, thinking that would get something out of it! Came out with a very dark base fog but very useable negs. I liked this one so much I made a 10x8 wet print, although this is a scan from a 3 1/2 x 5 1/2 proof print and as usual, the scan looks nowhere near as good as the print...
