Cameras

Cameras are optical devices that are used to capture and record visual images. They are commonly used in a wide range of applications, including photography, videography, surveillance, and scientific imaging. Cameras typically consist of a lens, which focuses the light onto a photosensitive surface, such as film or a digital image sensor, and an aperture, which controls the amount of light that reaches the image sensor. Most cameras also include a viewfinder or display, which allows the user to compose and frame the image, and various controls and settings that allow the user to adjust the camera's exposure, focus, and other parameters to suit the specific requirements of the scene being captured.
