Wired’s How-To Wiki has a short and sweet arti­cle on Pro­duc­ing Ter­rific Black & White Pho­tos. There’s a good tip for those who feel the need to go pho­tograph­ing on an over­cast day:

Most pho­tog­ra­phers will tell you that gloomy, over­cast days are per­fect for shoot­ing in black and white. So the next time the fog rolls in or the clouds hang a lit­tle too low, take it as your cue to get cre­ative with the shades of gray.
