With mirror lock-up the mirror (2) flips up towards (5) well before the shutter (3) opens. As a result, light no longer reaches the eyepiece (8). 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 ...
Schematic of an omnidirectional camera with two mirrors: 1. Camera 2. Upper Mirror 3. Lower Mirror 4. "Black Spot" 5. Field of View (light blue) In photography, an omnidirectional camera (from "omni", meaning all), also known as 360-degree camera, is a camera having a field of view that covers approximately the entire sphere or at least a full circle in the horizontal plane.
In the two-mirror schlieren system (sometimes called the Z-configuration), the source is collimated by the first mirror, the collimated light traverses the object and then is focused by the second mirror. This generally allows higher resolution imaging (seeing finer details in the object) than is possible using the single-mirror configuration.

Video feedback. Video feedback is the process that starts and continues when a video camera is pointed at its own playback video monitor.The loop delay from camera to display back to camera is at least one video frame time, due to the input and output scanning processes; it can be more if there is more processing in the loop.
In photography, the pellicle mirror has been employed in single-lens reflex (SLR) cameras, at first to enable through-the-lens exposure measurement and possibly to reduce camera shake, but later most successfully to enable fast series photography, which otherwise would be slowed down by the movement of the reflex mirror, while maintaining constant finder vision.
A camera's on-board monitor. While the traditional video tap no longer applies to modern CCD based cameras, large-scale productions with HD cameras still use video assist in its wider meaning. In this case, the video signal is fed from the camera's own video output, and is a significantly better quality than the original video tap technology.
Flip cameras' video quality was unusually good for their prices and sizes. [8] They can record videos at different resolutions. FlipHD camcorders digitally record high-definition video at 1280 x 720 resolution using H.264 video compression, Advanced Audio Coding (AAC) audio compression and the MP4 file format, while the older models used a 640 x 480 resolution.
