I just bought 3 1920's boxes of Kodak sheet film - hand dated as opened in Oct 1928-
most of the film is still in there, in layers of wrapping - of course no way to know if it has been opened carelessly in 90+ years
I did find it interesting that the spec sheet in there gives times for D-76 formula processing
there is no film speed shown on the box - I expect it was slow to start with
one box says Panchromatic, another Panchromatic super sensitive and the other says Portrait super speed
the boxes are in great condition - and that's the reason I got them - for display with the old cameras
but I figure what the heck- I'll try a couple sheets -
my thought is to shoot a high contrast image - with a fairly long exposure - maybe meter at a speed of 25 - and then give it a couple stops more
then cut the film into 5 strips and try extending the process time a few minutes for each strip to see what I get - sort of like a test strip when printing
not really expecting much out of it- but it will be fun to try
any suggestions? what is the oldest film you have tried?
I would suggest that you take an unexposed sheet and process it to see what the fog level is like, if it is relatively clear, make some photos with it. HC110 would be a good developer for the test.
