Tips for Black and White Photography
Though color photography is quite common, black and white photography is often a great choice for exploring your creativity. This article lists quick tips for black and white photography.
1. You can choose from different formats (different film sizes): 35mm (1″ x 1″), medium format- 120 (2″ x 2 “), and large format (4″ x 5″). Usually, beginning photographers will start off on a 35mm SLR (single-len reflex) camera. This camera allows the photographer to view and focus on the subject directly though the lens.
2. There are different film speeds for different situations; film speeds are rated by an ASA (American Standards Association) number. For brightly lit subjects, a slow film such as 32 ASA is used; slow film produces fine grain negatives. Outdoor photographers will typically use a medium film speed such as 125 ASA, and that produces medium grain negatives. A fast film speed, such as 400 ASA is best for indoor use, and produces coarse grain negatives.
3. The aperture is adjusted to control the amount of light entering the lens. F-stop is a measurement of the size of the lens opening. A smaller F-stop number is a bigger opening and allows more light to reach the film. A larger F-stop number decreases the amount of light that reaches the film. The following is a typical F-stop range: 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22.
4. Focal length is a measure of the lens size, measured in mm. For a lens with a longer focal length, the angle of view is narrower. A short focal length has a wider angle of view. The following are lens types and their focal lengths: normal (50mm), wide angle (21-35mm), and telephoto (105-300mm).
5. Shutter speed refers to the length of time the film is exposed to light. A fast shutter speed means the length of exposure time is short. A slow shutter speed means the length of exposure time is long. Shutter speeds: B, T, 2, 4, 8, 15, 30, 60, 125, 250, 500, 1000. Shutter speed time can be better understood if you place a 1 over the number to turn it into a fraction. When you place a 1 over the 2, that means the shutter speed is a second.
6. The B stands for bulb, and the T stands for time. Bulb means that the shutter will stay open for the amount of time you are pressing the button down. Time will keep the shutter open until you press the button again.
