How Cameras Work
The basic principle of photography is capturing light. A camera has a lens that focuses light onto an image sensor, which converts the light into an electrical signal. The electrical signal is then processed and stored in digital or film format.
Subheading 1: The Lens
- The lens is the part of the camera that controls the amount of light entering the camera.
- Lenses are typically measured in millimeters (mm), with smaller numbers indicating wider angles of view.
- The aperture of a lens is the opening that allows light to enter, and it is measured in f-stops (e.g., f/2.8, f/8).
Subheading 2: The Image Sensor
- The image sensor is the part of the camera that converts light into an electrical signal.
- Image sensors are typically made of silicon and contain millions of tiny light-sensitive pixels.
- The size of the image sensor is measured in megapixels (MP), with higher numbers indicating more pixels and potentially better image quality.
