Mirror lock-up (often abbreviated to MLU) is a feature employed in many Single Lens Reflex (SLR) cameras. It allows the operator to reduce vibration-induced motion blur during exposure. It also allows ...
The pellicle mirror causes an up to 1/3-stop loss of light at the receptor, and a corresponding 2-stop loss of light in the viewfinder; The mirror has to be kept perfectly clean, or the light sensor and other electronics (as well as the image quality) will suffer. Owing to its thinness, the pellicle mirror is fragile, making it difficult to clean.
When blocking the light, the exposed portion of the film is advanced, and another, pristine frame is moved into position. The spinning disc then exposes the new frame of film. The nature of light-sensitive film requires a shutter to block the light and prevent smearing of the image as the film is advanced through the camera. Digital sensors do ...
A mirror, also known as a looking glass, is an object that reflects an image. Light that bounces off a mirror will show an image of whatever is in front of it, when focused through the lens of the eye or a camera.

Hot mirror in front of the image sensor of a DSLR. Note reddish reflection of ambient light, and teal edge of filter.
