The exposure time, that is, the time when the camera shutter is open, is called shutter speed, from the word "hold" (shutter open). Two points are important here. First, shutter speed is associated with the process of obtaining light on a matrix or film, and therefore interacts very closely with the diaphragm. Secondly, exposure is also the process of irradiation of a light-sensitive material, that is, the light sensitivity of the material is important, which is usually denoted by ISO, which also affects the exposure.
Instructions
Step 1
Most cameras use the same shutter speed scale, which is expressed in fractions of a second: These are indicators from 8000 (18000 seconds) to 4 (4 seconds). A fast shutter speed is required so as not to blur the frame, because if you hold the camera in your hands, then the focus can be shifted from the slightest fluctuation. If you are shooting without a tripod, it is always necessary to aim for a faster shutter speed so that the shots are clearer. If there is a lot of light, then the ISO should be minimal. If the day is cloudy, the ISO should be between 200-400.
Step 2
The slowest shutter speed (1/8000) is used for moving subjects. But the photosensitivity (ISO) for such shooting should be maximum.
Step 3
If there is little light, then the shutter speed is increased. The slowest shutter speed is set when shooting at night without using a flash. Light sensitivity should be maximized as well, and the aperture should be open.
