An ultra wide-angle lens is a lens whose focal length is shorter than that of an average wide-angle lens, providing an even wider view. The term denotes a different range of lenses, relative to the size of the sensor in the camera in question. [1] For 1" any 9mm or shorter is considered ultra wide angle. For 4/3" any 10 mm or shorter lens is ...
Ultrawide formats refers to photos, videos, [ 1] and displays [ 2] with aspect ratios greater than 2. There were multiple moves in history towards wider formats, including one by Disney, [ 3] with some of them being more successful than others. Cameras usually capture ultra-wide photos and videos using an anamorphic format lens, which shrinks ...
A wide-angle lens is also one that projects a substantially larger image circle than would be typical for a standard design lens of the same focal length. This large image circle enables either large tilt & shift movements with a view camera . By convention, in still photography, the normal lens for a particular format has a focal length ...
Ultraviolet photography is a photographic process of recording images by using radiation from the ultraviolet (UV) spectrum only. Images taken with ultraviolet radiation serve a number of scientific, medical or artistic purposes. Images may reveal deterioration of art works or structures not apparent under light.
Different kinds of camera lenses, including wide angle, telephoto and speciality. A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.
A polarizing filter or polarising filter (see spelling differences) is a filter that is often placed in front of a camera lens in photography in order to darken skies, manage reflections, or suppress glare from the surface of lakes or the sea. Since reflections (and sky-light) tend to be at least partially linearly-polarized, a linear polarizer ...
Thus a blue filter makes the picture look blue. A blue filter marginally allows more light in the blue wavelength to pass resulting in a slight shift of the color temperature of the photo to a cooler color. Because of this, the term "IR filters" is commonly used to refer to filters that pass infrared light while completely blocking other ...
The Wide Field and Planetary Camera 2 ( WFPC2) is a camera formerly installed on the Hubble Space Telescope. The camera was built by the Jet Propulsion Laboratory and is roughly the size of a baby grand piano. It was installed by servicing mission 1 ( STS-61) in 1993, replacing the telescope's original Wide Field and Planetary Camera (WF/PC).
