An optical camera is a device that captures images using light. It typically consists of a lens that focuses light onto a sensor or film, allowing for the creation of photographs. The lens can be adjusted to change the focus and zoom, enabling the photographer to capture subjects at various distances and sizes. Optical cameras come in various types, including digital cameras, DSLRs, and mirrorless cameras. Each type has its own features and advantages, but they all rely on the principles of optics to produce clear and detailed images. The quality of the captured image depends on factors like lens quality, sensor size, and lighting conditions.
