A while back acquired many boxes of mostly 11x14 film from our State's surplus store for just a few dollars. Among them are:
PREMIUM HD NEGATIVE FILM
TYPOAQUE TR-DO film
KODAK BIOMAX
KODAK Special PX-2836
Kodak Precision Line
Agfa TP5F (lot of boxes of this film)
2 unlabeled (but the same looking) boxes
So now I have time on my hands to try out these films to see if any are even useable. Was thinking of cutting up sheets of the films to 8x10, and also cutting up 2 dark slides so that I could make 4 different exposures on each sheet of film.
Shoot 4 exposures on each sheet at ISOs of 1.0, 4, 25, and 100.
Punching/notching the edges of the films to know which is which after precessing. Also shooting 2 sheets of FP-4+ as a known standards to compare the results of the other films with. Do this twice with sheets my "unknown" films, then process one batch in Rodinal 1:25 for 10 minutes and the other batch in Rodinal 1:100 for 20 minutes. With processing 4 runs using my JOBO 3005 tank, should be able to get some useable results/data.
Would very much welcome comments and/or suggestions before doing this.
Thanks
