eksponeerimisparameetrite

Eksponeerimisparameetrite is a term used in photography to describe the settings that control how much light reaches the camera's sensor. These parameters are crucial for achieving a properly exposed image, meaning a picture that is neither too dark nor too bright. The three primary eksponeerimisparameetrite are aperture, shutter speed, and ISO.

Aperture refers to the size of the opening in the lens that allows light to pass through. It is measured in f-stops, where a smaller f-number indicates a larger opening and thus more light. Aperture also affects the depth of field, which is the range of distances in a scene that appear in focus. A wider aperture (smaller f-number) results in a shallower depth of field, blurring the background, while a narrower aperture (larger f-number) creates a greater depth of field, keeping more of the scene in focus.

Shutter speed determines the duration for which the camera's sensor is exposed to light. It is measured in seconds or fractions of a second. A faster shutter speed (e.g., 1/1000th of a second) freezes motion and allows less light in, while a slower shutter speed (e.g., 1 second) can create motion blur and allows more light.

ISO refers to the sensitivity of the camera's sensor to light. A lower ISO setting (e.g., 100) means the sensor is less sensitive to light and produces cleaner images with less digital noise. A higher ISO setting (e.g., 3200) increases the sensor's sensitivity, allowing for shooting in low light conditions, but it also introduces more noise into the image. Adjusting these three parameters in combination allows photographers to control the brightness, appearance, and creative effects of their photographs.
