Fujix DS-1P
The Nikon E series, co-developed with Fujifilm, are autofocus 1.3 megapixel professional grade quasi-full frame (35mm) Nikon F-mount digital single lens reflex cameras ( DSLR) manufactured by Nikon since 1995. The E series included the ''Nikon E2/E2S'', ''Nikon E2N/E2NS'' and the ''Nikon E3/E3S''. The S-variants are identical except they had triple the frame rate and a larger buffer. Its unique optical system bundles the light of the full-frame lenses to the small 2/3 inch CCD sensor. That gives approximately 4 stops more light at the small sensor, therefore delivering an exceptional (for that time) minimum sensitivity of 800 and maximum 3200 ISO, which remains usable for press and news use. Technology The Nikon E2/E2S and E2N/E2NS use a Nikon F4 subsystem, the E3/E3S uses a Nikon F100 subsystem. Optical system The E series uses a unique additional optical system that enables the small sensor to capture the field of view of a 35mm film, with a crop factor of 1. T ...

Digital Single Lens Reflex Camera
A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor. The reflex design scheme is the primary difference between a DSLR and other digital cameras. In the reflex design, light travels through the lens and then to a mirror that alternates to send the image to either a prism, which shows the image in the viewfinder, or the image sensor when the shutter release button is pressed. The viewfinder of a DSLR presents an image that will not differ substantially from what is captured by the camera's sensor as it presents it as a direct optical view through the main camera lens, rather than showing an image through a separate secondary lens. DSLRs largely replaced film-based SLRs during the 2000s. Major camera manufacturers began to transition their product lines away from DSLR cameras to mirrorless interchangeable-lens cameras (MILC) beginning in the 2010s. ...

Space Shuttle STS-70 Launch DSC00001
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the ''Timaeus'' of Plato, or Socrates in his reflections on what the Greeks called ''khĂ´ra'' (i.e. "space"), or in the ''Physics'' of Aristotle (Book IV, Delta) in the definition of ''topos'' (i.e. place), or in the later "geometrical conception of place" as "space ...

Photokina 1986
Photokina (rendered in the promoters' branding as "photokina") is a trade fair held in Europe for the photographic and imaging industries. It is the world's largest such trade fair. The first Photokina was held in Cologne, Germany, in 1950, and since 1966 it has been held biennially in September at the Koelnmesse Trade Fair and Exhibition Centre in Deutz. The final Photokina under the then-current biennial cycle took place in 2018. Initially, the promoters planned to start a new annual cycle in 2019, with future shows to be held in May, but they later decided not to begin the new annual cycle until 2020. The worldwide outbreak of the Coronavirus disease 2019 and its effect on the imaging industry made Koelnmesse decide to cancel both Photokina 2020 and Photokina 2021. Many photographic and imaging companies introduce and showcase state of the art imaging products at Photokina. Similar trade shows The show has two main competitors, both of which are annual shows held in differe ...

Still Video Camera
A still video camera (SVC) is a type of electronic camera that takes still images and stores them as single frames of video. They peaked in popularity in the late 1980s and can be seen as the predecessor to the digital camera. However, unlike the latter, the image storage in such cameras is based on analog technology, rather than as a digital file. Design The most common design has an image sensor and basic processing hardware similar to that of a consumer camcorder designed for analog television using the appropriate regional format (NTSC, PAL, or SECAM). However, instead of storing consecutive interlaced fields on tape to form a moving image, a single field or frame (combined from two fields) is extracted from the output video signal and saved on a rotating magnetic disk, typically a standard Video Floppy. During playback, the disk is spun at the frame rate of the video system with the field or frame being read repeatedly. This produces a conventional analog video signal that can ...

Electrical Connector
Components of an electrical circuit are electrically connected if an electric current can run between them through an electrical conductor. An electrical connector is an electromechanical device used to create an electrical connection between parts of an electrical circuit, or between different electrical circuits, thereby joining them into a larger circuit. Most electrical connectors have a genderi.e. the male component, called a ''plug'', connects to the female component, or ''socket''. The connection may be removable (as for portable equipment), require a tool for assembly and removal, or serve as a permanent electrical joint between two points. An adapter can be used to join dissimilar connectors. Thousands of configurations of connectors are manufactured for power, data, and audiovisual applications. Electrical connectors can be divided into four basic categories, differentiated by their function: * ''inline'' or ''cable'' connectors permanently attached to a cable, so it ...

SCSI
Small Computer System Interface (SCSI, ) is a set of standards for physically connecting and transferring data between computers and peripheral devices. The SCSI standards define commands, protocols, electrical, optical and logical interfaces. The SCSI standard defines command sets for specific peripheral device types; the presence of "unknown" as one of these types means that in theory it can be used as an interface to almost any device, but the standard is highly pragmatic and addressed toward commercial requirements. The initial Parallel SCSI was most commonly used for hard disk drives and tape drives, but it can connect a wide range of other devices, including scanners and CD drives, although not all controllers can handle all devices. The ancestral SCSI standard, X3.131-1986, generally referred to as SCSI-1, was published by the X3T9 technical committee of the American National Standards Institute (ANSI) in 1986. SCSI-2 was published in August 1990 as X3.T9.2/86-109 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Available Light
In photography and cinematography, available light (also called ambient light or practical light) refers to any ''available'' source of light that is not explicitly supplied by the photographer for the purpose of taking pictures. The term usually refers to light sources in the surrounding environment that are present naturally (e.g. sunlight, moonlight, starlight, etc.) or artificial lighting that are already pre-existing (e.g. street lights, room lights, etc.). It generally excludes flashes, although arguably flash lighting provided by other photographers shooting simultaneously in the same space could be considered available light. Light sources that affect the scene and are included in the actual frame are called practical light sources, or simply practicals. Use of available light is an important factor in candid photography in order not to disturb the subjects. The use of available light may pose a challenge for a photographer. The brightness and direction of the light ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Speed
In everyday use and in kinematics, the speed (commonly referred to as ''v'') of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity. The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. Speed is not the same as velocity. Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second (m/s), but the most common unit of speed in everyday usage is the kilometre per hour (km/h) or, in the US and the UK, miles per hour (mph). For air and marine travel, the knot is commonly used. The fastest possible speed at which energy or information can travel, according to special relativity, is the speed of light in a vacuum ''c'' = metres per second ...
