Film doesn't display banding, as film grains are distributed randomly. Banding is an artifact of the sensor grid. Digital doesn't tolerate underexposure all that well. It's like slide film in that area. Try underexposing ISO 1600 slide film by 2 stops and see what the results are. They won't be pretty. Note that underexposing 1600 speed B&W film by 2 stops will not produce good results. This is effectively a push to ISO 6400, without development compensation. I've done this in the past, and the results aren't pretty. -Adam -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
