How does a camera work simple explanation?
A camera lens takes all the light rays bouncing around and uses glass to redirect them to a single point, creating a sharp image. … When all of those light rays meet back together on a digital camera sensor or a piece of film, they create a sharp image.
What happens immediately after light enters a digital camera?
In a digital camera, exactly the opposite happens. Light from the thing you are photographing zooms into the camera lens. This incoming “picture” hits the image sensor chip, which breaks it up into millions of pixels. The sensor measures the color and brightness of each pixel and stores it as a number.
What controls how long light enters the camera?
1. Aperture. Like the iris of your eye, the aperture blades on the lens of a camera control how much light is let into the camera lens.
Why do I look bad on camera?
The most common cause of camera distortion is that the subject is too close to the lens. Most photographers say that the type of lens used also has a lot to do with it, and wide-angle lenses (like the ones in our camera phones) are big offenders.

What is the purpose of aperture?
In photography. The aperture stop of a photographic lens can be adjusted to control the amount of light reaching the film or image sensor. In combination with variation of shutter speed, the aperture size will regulate the film’s or image sensor’s degree of exposure to light.
What does digital camera mean?
A digital camera or digicam is a camera that captures photographs in digital memory. … However, unlike film cameras, digital cameras can display images on a screen immediately after being recorded, and store and delete images from memory. Many digital cameras can also record moving videos with sound.
What are the two most important exposure controls?
The two most important exposure controls are the shutter speed and aperture because both affect the total amount of light reaching the image sensor. However, they do more than just control the exposure.
What are the three basic camera settings?
Believe it or not, this is determined by just three camera settings: aperture, ISO and shutter speed (the “exposure triangle”). Mastering their use is an essential part of developing an intuition for photography.
What is the difference between ISO and exposure?
ISO is a measure of the sensitivity of the image sensor or film used in a camera. … At higher sensitivity like (1600 ISO) less light is required. So exposure is the actual amount of light the sensor is exposed to and ISO is one of the factors that determine the amount of light needed for a proper exposure.
