When shooting black and white photography using natural light, you should let the situation dictate the look and feel of the photo. So don't set out and try to shoot a high contrast shot unless you find a good opportunity with the right lighting. Try shooting on an overcast day.

Colors can easily be distractions in a photo, since they're some of the first things our eyes gravitate toward in a frame. If you consider the colors in your shot to be ugly or distracting, and you don't want a viewer's eye to gravitate there, black and white is a great solution.

White balance (WB) is the process of removing unrealistic color casts, so that objects which appear white in person are rendered white in your photo. Proper camera white balance has to take into account the "color temperature" of a light source, which refers to the relative warmth or coolness of white light.
