i honestly never make black and white photos, i just prefer to catch the moment the way it is... but i do like some monocromatic pictures, depends on the subject and the context really, but i prefer to see others works on this matter
all i remember of the old times were when you had a camera with a single roll inside, you would just click and never know how it came out until you printed them, and the camera had a sort of counter to help you count how many shots left
