Bridge cameras employ two types of electronic screens as viewfinders: The LCD and the electronic viewfinder (EVF). All bridge cameras have an LCD with live-preview and usually in addition either an EVF or an optical viewfinder (OVF) (non-parallax-free, as opposed to the OVF of DSLRs, which is parallax-free). A high-quality EVF is one of the ...
A twin-lens reflex camera (TLR) is a type of camera with two objective lenses of the same focal length. One of the lenses is the photographic objective or "taking lens" (the lens that takes the picture), while the other is used for the viewfinder system, [ 1 ] which is usually viewed from above at waist level.
One-way glass (4) used in a teleprompter. A one-way mirror is typically used as an apparently normal mirror in a brightly lit room, with a much darker room on the other side. People on the brightly lit side see their own reflection—it looks like a normal mirror. People on the dark side see through it—it looks like a transparent window. The ...
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 ...
It is also possible to create a twin camera rig, together with a "shepherd" device to synchronize the shutter and flash of the two cameras. By mounting two cameras on a bracket, spaced a bit, with a mechanism to make both take pictures at the same time. In 2009 digital stereo cameras such as the Fuji W1 began appearing in the consumer market.

Two thirds of the light from the camera lens was let through the mirror, while the rest was reflected up to the viewfinder screen. [4] The Pellix pellicle mirror was an ultra-thin (0.02 mm) Mylar film with a vapour deposited semi reflecting layer. Since there was no mirror blackout, the user could see the image at the moment of exposure. [5]
