BACK SHUTTER Meaning and
Definition
-
A back shutter refers to a device or mechanism located at the rear end of a camera lens, primarily found in large format cameras and certain specialized photography equipment. It serves the purpose of controlling the exposure of light onto the photographic material, usually a film or a photosensitive plate, by blocking or allowing light to pass through.
The back shutter consists of a set of overlapping metal blades or curtains that can be adjusted to various positions, including open and closed, with different speeds and settings. When the back shutter is closed, it prevents light from reaching the photosensitive medium, thus ensuring proper framing and preventing any unintended exposure or light leakage. By opening the back shutter, the lens allows light to expose the film or photosensitive plate placed in the focal plane, capturing the desired image.
The back shutter is essential in photography as it enables photographers to control the exposure time and adjust shutter speeds. It contributes to the overall image quality and determines the final appearance and sharpness of the photograph. Additionally, the back shutter also protects the film or photosensitive material from damage and unwanted exposure when changing scenes or transporting the camera.
Overall, the back shutter is a vital component in traditional photography, providing control, precision, and protection in the creation of images on film or photosensitive plates.
