Camera A camera is an optical instrument used to capture and record images, either electronically or on photographic film. Modern cameras come in various types and formats, including digital cameras, film cameras, DSLRs (Digital Single-Lens Reflex), mirrorless cameras, and compact cameras. Cameras consist of several essential components, including a lens, image sensor (or film), viewfinder (or digital display), shutter mechanism, and control interface.
They function by focusing light through the lens onto the sensor or film, where the image is recorded. Digital cameras convert light into electrical signals, which are then processed and stored digitally, while film cameras expose light-sensitive film to capture images chemically. Cameras play a fundamental role in photography, enabling photographers to capture moments, express creativity, and document the world around them. |
