Color photography seems to be all the rage nowadays, but black and white photography can provide nuance and a certain level of sophistication to your work. Below are quick tips for black and white photography.
1. There are many different sizes of film, and different formats: 35mm (1" x 1"), medium format- 120 (2" x 2 "), and large format (4" x 5"). Typically, people will start off using a 35mm SLR (single-lens reflex) camera. With an SLR, you can focus and view the subject directly through the lens.
2. Different film speeds are chosen for different situations and are rated by an ASA (American Standards Association) number. A slow film is 32 ASA and is used for brightly lit subjects; it produces fine grain negatives. 125 ASA produces medium grain negatives, and is chosen for outdoor use. 400 ASA is a faster film and is best for indoor use and results in coarse grain negatives.
3. Aperture settings control the amount of light entering the lens. A measurement of the size of the lens opening is called F-stop. A small F-stop is a bigger opening exposing the film to more light. A large F-stop is a smaller opening and decreases the amount of light reaching the film. F-stop ranges: 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22.
4. There are different sized lenses, and they are distinguished by focal length (measured in mm). A wide angle view corresponds to a short focal length. A narrow angle view corresponds to a long focal length. A few lens types and focal lengths: normal (50mm), wide angle (21-35mm), and telephoto (105-300mm).
5. The shutter speed determines the time the film is exposed to light. The faster the shutter speed, the less time light is exposed to the film. A slow shutter speed means that the film is being exposed to light for a longer amount of time. The following are shutter speeds: B, T, 2, 4, 8, 15, 30, 60, 125, 250, 500, 1000. You can determine the time the shutter is open by placing a 1 over each number to get a fraction. For example, 2 means the shutter is open for on half of a second
6. Regarding shutter speed, the B means bulb, and the T means time. When using bulb, you just hold the button down for the desired amount of time. When using time, the second time you press down the button is when the shutter closes.
