Here’s how a digital camera works, and an overview of the more important camera parts.
All cameras and camcorders basically use the same principle, where light that is reflected off the subject is captured by the sensor to recreate the image.
Checkout this video to get an idea of how it is done!
It explains how a basic digital camera works with a CMOS sensor. This is the basis for most modern video/cameras.
Lens
The lens is what captures the light and focuses it on the film/sensor. The lens is positioned at the correct focusing distance from the film/sensor by a focusing mechanism.
On some cameras, this length is fixed however on most cameras you have control over the focal length.

Shutter
Another important part of the camera, a shutter prevents the entered light reaching the film/sensor until you press the release button allowing you to decide exactly when to take the picture.
The beginner models usually do not let you change the shutter speed, and it is typically set at 1.125 second. The more expensive ones however allow you to select from a range of speed settings. This way you can either “freeze” / “blur” moving subjects, or compensate for dim / bright lighting conditions.
Lens Aperture
A lens aperture is an adjustable circular hole positioned within or just behind the lens. It is used to control the amount of light / brightness of an image.
Usually, the smaller the aperture, the more parts of the scene will appear in focus, and the greater is the “depth of field”.
As you can see, this along with the shutter, are the controls you have at your disposal to adjust the light that your image receives.
Viewfinder
A viewfinder allows you to preview the picture. There are two types of viewfinders, one that is found on non-reflex cameras (they have a direct viewfinder) and the other that is available on SLR cameras.
Single lens reflex (SLR) cameras allow you to view the actual image formed by the lens. Direct viewfinders are bright and clear, but less accurate than SLR for composing images, particularly close-ups.
The LCD is another important component that displays all the menu options and also lets you know how many pictures you have taken.
So these are more or less the more important parts of a camera!
