Camera

A camera is an optical instrument that captures and records images or videos, either on film or via a digital sensor. It works by allowing light to pass through a lens and a controllable aperture, focusing it onto a light-sensitive surface to create a, often inverted, image.
Key Components & Functions
Body: A light-tight container that houses the internal components.
Lens: Focuses light from the subject onto the sensor or film.
Aperture & Shutter: The diaphragm (aperture) regulates the amount of light entering, while the shutter controls the duration of exposure.
Sensor/Film: Captures the image, with modern cameras using digital sensors (CCD or CMOS) to create digital files, and traditional cameras using light-sensitive film.
Common Camera Types
Digital Camera: Stores photos digitally, allowing instant viewing and deletion.
DSLR (Digital Single-Lens Reflex): Uses a mirror system to reflect light into an optical viewfinder, with interchangeable lenses.
Mirrorless Camera: Similar to DS
