Each tick away from the TECHPan/POTA and ISO 12/25 combo produces increased contrast. ISO 50 is about tops for producing a "full" tonal range print. When you approach ISO 400, you are talking document copying and linecopy activities. Your discovery is correct; this film has no equals and is truly remarkable. Randolph Carlisle
