If you come across something to photograph and think to your self "this would make an awesome black and white" do you do anything different that you normally wouldn't do if you were shooting with the intent of leaving it in colour? Or do you do everything the same until post?
I'm one of the people who advocates for shooting RAW + JPEG Monochrome in-camera, with a color filter effect applied, such as the Yellow Filter, and also the Sepia image toning applied to the jpegs the camera creates, as well as setting the sharpening fairly high. What this does is it gives you a sharpened SOOC JPEG image, but much,much,much more-importantly, it allows you to actually SEE for yourself, with your own eyes, at the time you're shooting, what the shot looks like in B&W. Actually shooting, reviewing, and evaluating and making adjustments to an on-the-back-of-the-camera B&W image gives you a big advantage over "imagining" how good the subject will look in B&W. Some subjects are gonna SUCK as B&W's because the lighting, or the type of subject matter, just does not work well for a B&W image.
Black and white images rely on contrast, and
tonal variations. If you do not apply a filter effect in-camera, you'll see blue skies rendered ugly white. Black and white images work better with a bit higher contrast lighting than most color images; when color is removed, things tend to blend together,mush together. A color shot and a B&W image can have vastly different lighting; B&W emphasizes lines, shapes, masses, tonal variations and tonal differences, B&W works great to show patterns, to show repetition, to show dissonant elements. B&W works great when shooting contre jure, or "toward the light" or "against the daylight", whatever translation you want to apply to the French word. B&W works well with harder light that reveals dimensionality via shadows, and via showing texture through angled light, or sidelight, or raking light. If a subject has a lot of similar tonal values, like say, a LOT of light, pastel hues...it's not going to look the same in B&W if everything is "light" and "pastel".
B&W reveals a subject in fundamentally different ways than full-color does. Watch a late 1940's or early 1950's film noir movie, and see what outlandishly high lighting ratios look like when filmed in B&W, then compare a modern film, shot and lighted for COLOR. One of the best pieces of advice I ever got was, when lighting for color, use smaller light modifiers, or more high-contrast lighting than you would when shooting for color.
