« Back to Glossary Index
Camera is a device used to capture still images or moving video by recording light, either digitally or on film. It typically consists of a lens that focuses light onto a sensor (in digital cameras) or film (in analog cameras), and a shutter that controls the duration of exposure. Modern digital cameras, including those in smartphones, use electronic sensors such as CCD or CMOS to convert light into digital data, allowing for immediate viewing, editing, and sharing. Cameras vary widely in design and function—from professional DSLRs and mirrorless cameras to compact point-and-shoots and integrated smartphone cameras—each offering different features for various photography needs.
