Response to Diafine: Tri-x @ 1000-1600. Is this a joke?

conrad's right. pushing is basically a myth. if you don't have enough light when metering at iso 400, what good does it do to underexpose 3 more stops by metering with an iso 1600. for every film there is a minimum amount of exposure needed before density starts to build up on the negative. if the exposure is not enough in the low values (print values II and III) there is little you can do to significantly build up the image.
