Old video camera viewfinder cutway; note the miniature CRT An Olympus PEN E-PL5 mounted with an external EVF unit: the Olympus VF-4 EVF of Panasonic Lumix DMC-G85/G80 with 2,360,000 dots. An electronic viewfinder ( EVF ) is a camera viewfinder where the image captured by the lens is displayed on a small screen (usually LCD or OLED ) which the ...
EVF: Electronic viewfinder. The through-the-lens view is displayed on a miniature solid-state screen, rather than on an optical screen or view. [2] EVIL: Electronic viewfinder interchangeable lens camera. See also MILC, mirrorless interchangeable-lens camera. [16] Exif: Exchangeable image file format. A standard format for tag data in digital ...
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 ...
In photography, a viewfinder is a device on a camera that a photographer uses to determine exactly where the camera is pointed, and approximately how much of that view will be photographed. A viewfinder can be mechanical (indicating only direction and approximate view), with simple optical components, with precision optics and optical functions ...
Live preview on LCD. The concept for cameras with live preview largely derives from electronic TV cameras.Until 1995 most digital cameras did not have live preview, and it was more than ten years after this that the higher end digital single-lens reflex cameras (DSLR) adopted this feature, as it is fundamentally incompatible with the swinging-mirror single-lens reflex mechanism.
Extended exposure time of 26 seconds. Exposure value is a base-2 logarithmic scale defined by (Ray 2000, 318): = = , where N is the f-number; and; t is the exposure time ("shutter speed") in seconds [2]
A lever on the front of the camera switches between EVF and OVF with the OVF providing clear framelines and the view outside of these framelines leading to the X-Pro series being popular with street photographers to see what might be entering their shot.
A demonstration of the effect of exposure in night photography. Longer shutter speeds result in increased exposure. The true characteristic of most photographic emulsions is not actually linear (see sensitometry), but it is close enough over the exposure range of about 1 second to 1/1000 of a second. Outside of this range, it becomes necessary ...
