Final answer:
In photography, the three primary features to look for in a quality exposure system are shutter speed, aperture, and ISO.
Step-by-step explanation:
The three primary features to look for in a quality exposure system in photography are shutter speed, aperture, and ISO.
Shutter speed refers to the length of time the camera's shutter remains open, determining how much light enters the camera. A faster shutter speed can freeze motion, while a slower speed can create motion blur.
Aperture refers to the adjustable opening of the camera's lens, controlling the amount of light that reaches the camera's sensor. A wider aperture (lower f-stop number) allows more light and creates a shallow depth of field, while a narrower aperture (higher f-stop number) allows less light and creates a greater depth of field.
ISO measures the sensitivity of the camera's sensor to light. A lower ISO setting is less sensitive and produces cleaner, less noisy images, while a higher ISO setting is more sensitive but may result in more noise.
