For most black and white photographers, a simple flash unit-either bulb or electronic-mounted on top of the camera provides the easiest means for supplying needed light. An adequately exposed black and white picture is almost guaranteed if the simple instructions that come with the unit are followed. But the trouble is that the black and white picture almost always comes out flat, the subject two dimensional, with details bleached out by the head-on burst of light (broad faces are made still broader looking). The fault lies not with the flash itself but with the way it is used. More natural-looking results, with a livelier, three-dimensional quality, can be obtained by employing such simple tricks as those demonstrated at right. These techniques make any artificial light more nearly resemble natural illumination. Since almost all natural light household lamp or a ceiling fixturing whether supplied by a window, comes from above the subject, the most natural-looking black and white pictures will result from a flash held above the level of the lens and slightly to one side or bounced in such a way that light comes from above. But natural black and white Lighting , indoors or outdoors, rarely strikes a subject from one direction alone; covering the flash with a diffusing screen, bouncing some of its light off walls and adding a second or third flash all help give a multidirectional quality to the light, creating the soft shadows, interesting textures and lifelike depth that most people prefer in their black and white photographs. Direct flash on camera: For the majority of black and white photographers, especially when they want to catch a fleeting moment, this is the quickest and simplest method, but the light is often flat and uninteresting, producing few of the shadows or textures that add roundness and sparkle. Bounced flash: For soft natural-looking black and white Lighting , with good modeling of features, the flash unit (whether on or oft the camera) can be tilted so that its light does not reach the subject directly but is reflected off a white or light colored wall, as here, or a ceiling.
