hi michel:

great to see you posting again, and thanks for reactivating this thread.
i never saw it when you originally posted it ... and i for a long while was shooting
tech pan for high contrast ...
i shot a lot of backlit leaves and even a minute area of the film could easily be enlarged ( 35mm ) to 11x14 and larger with no grain &c
i also used it in 4x5 this way ...
a friend got married back in maybe 1997 and i shot his whole wedding using this film ... rating it at about 200 and processing it in gaf universal developer ( like ansco 130 ) 1:2 and got beautiful results. what was so nice was the images weren't pure black and pure white, but there were some midtones in there once in a while ...
