Final answer:
Shutter speed in photography is the exposure time calculation. A faster shutter speed allows less light and freezes motion, while a slower shutter speed allows more light and creates motion blur. Aperture setting determines the size of the lens opening and affects the depth of field.
Step-by-step explanation:
Shutter speed is the exposure time calculation in photography. It refers to the amount of time the camera's shutter is open, allowing light to pass through and hit the camera sensor or film. The shutter speed is represented as a fraction in the form of numerator/denominator, such as 1/200 or 1/1000.
A faster shutter speed (e.g., 1/1000) allows less light to enter the camera, resulting in a shorter exposure time. It is commonly used to freeze motion and capture fast-moving subjects. On the other hand, a slower shutter speed (e.g., 1/30) allows more light to enter the camera, resulting in a longer exposure time. It is often used to create motion blur or capture low-light scenes.
The aperture setting, represented by f-stop values (e.g., f/2.8, f/5.6), determines the size of the camera's lens opening. A wide-open aperture (e.g., f/2.8) allows more light to pass through and results in a shallow depth of field, where only a small portion of the image is in focus. A small aperture (e.g., f/16) restricts the amount of light and increases the depth of field, making more of the image appear in focus.
