Camera technology
A camera is a device that captures images, either still pictures or video, by recording light. It works by allowing light to enter through a lens, which focuses the light onto a sensor or film. The sensor or film then converts this light into an electrical signal or chemical reaction, creating an image. Cameras can be found in various forms, from digital cameras and smartphones to professional DSLR and mirrorless cameras. They allow us to preserve memories, document events, and express creativity through photography. Modern cameras often include features like autofocus, image stabilization, and connectivity for sharing images easily.

Camera technology involves capturing images through a combination of optical and electronic processes. Light enters the camera through a lens, which focuses it onto a sensor (in digital cameras) or film (in traditional cameras). The sensor converts light into electrical signals, which are then processed to create an image. Key components include the aperture (which controls light entry), shutter speed (which determines exposure time), and ISO (sensitivity to light). These elements work together to influence the final image quality, allowing for creativity in photography by adjusting settings to suit lighting conditions and desired effects.
