A camera is an instrument wont to record images. At their most elementary , cameras are sealed boxes (the camera body) with alittle hole (the aperture) that allow light in to capture a picture on a light-sensitive surface (usually film or a digital sensor). Cameras have various mechanisms to regulate how the sunshine falls onto the light-sensitive surface. Lenses focus the sunshine entering the camera, the dimensions of the aperture are often widened or narrowed to let more or less light into the camera, and a shutter mechanism determines the quantity of your time the photo-sensitive surface is exposed to the sunshine .
