The Metafilter thread has some interesting comments and questions: “One difference between film and digital, before the darkroom, is that with a digital camera, you don’t have anywhere near the wide range of different films available. I’ve started to take into account the characteristics of the film I’m using, or, conversely, select film depending on what I’m going to be photographing. Since this variety of effects is not available to digital ‘film’, I believe digital photography should be given more latitude with after-effects.”
