I know that it is normal practice, for some, to over expose their B&W film. I also know that it is a no no to over expose slide film, better to under expose if you have to. So what about black and white film for reversal? I love doing reversal processing with normal (?) black and white film. I never really thought about it until today, when i was taking some pix of some Canadian geese. should i expose the film at box speed, my rated speed for ned processing based on testing or bracket and figure it out? i did it at box speed as i have alwasys done nwith my specific film for rev processing. anyway.... what are your thoughts on this? film speed of B&W film for rev processing vs normal neg processing?
