>>4245200For b+w absolutely, with rodinal it's so easy and you can get your pictures in hours instead of weeks. If you don't have a tank already there is some expense I suppose.
The problem with color (and even worse for slide) is the chemicals go bad so quickly and are expensive so you don't want to mix up a fresh batch just for a roll or two. So you end up saving rolls up and not getting your pictures any sooner. But it does give you some more options, like remjet films.
