With black & white, you are looking for textures, lines, and contrast between elements in the scene. Analyze the scene before you shoot. If the main thing that attracts you is something bright colored, shot might not work. If the main that that attracts you are the lines & shapes, b&w probably will work. Buy three filters: green, orange, blue, red. Hold on a minute. Maybe that was four filters. Anyway, buy the filters and learn what effect each has on what color. Example. Where I am, the ground is covered with white snow, and today the sky is blue. If I were to shoot b&w with a red #29 filter, the ground would stay white and the sky would turn black. That can be pretty cool.
