Apple QuickTake
The Apple QuickTake (codenamed ''Venus'', ''Mars'', ''Neptune'') is one of the first consumer digital camera lines. It was launched in 1994 by Apple Computer and was marketed for three years before being discontinued in 1997. Three models of the product were built including the 100 and 150, both built by Kodak; and the 200, built by Fujifilm. The QuickTake cameras had a resolution of 640 x 480 pixels maximum (0.3 Mpx). ''Time'' magazine profiled QuickTake as "the first consumer digital camera" and ranked it among its "100 greatest and most influential gadgets from 1923 to the present" list. Although the greyscale Dycam Model 1 (also marketed as the Logitech FotoMan) was the first consumer digital camera to be sold in the US (starting in November 1990) and at least one other camera, the Fuji DS-X, was sold in Japan even earlier, in late 1989, the QuickTake was probably the first digicam to have wide consumer acceptance.

Apple Quicktake 100 (329044100)
An apple is an edible fruit produced by an apple tree (''Malus domestica''). Apple trees are cultivated worldwide and are the most widely grown species in the genus ''Malus''. The tree originated in Central Asia, where its wild ancestor, ''Malus sieversii'', is still found today. Apples have been grown for thousands of years in Asia and Europe and were brought to North America by European colonists. Apples have religious and mythological significance in many cultures, including Norse, Greek, and European Christian tradition. Apples grown from seed tend to be very different from those of their parents, and the resultant fruit frequently lacks desired characteristics. Generally, apple cultivars are propagated by clonal grafting onto rootstocks. Apple trees grown without rootstocks tend to be larger and much slower to fruit after planting. Rootstocks are used to control the speed of growth and the size of the resulting tree, allowing for easier harvesting. There are more th ...

Kodak DCS 100
The Kodak Professional Digital Camera System or DCS, later unofficially named DCS 100, was the first commercially available digital single-lens reflex (DSLR) camera. It was a customized camera back bearing the digital image sensor, mounted on a Nikon F3 body and released by Kodak in May 1991; the company had previously shown the camera at Photokina in 1990. Aimed at the photo journalism market in order to improve the speed with which photographs could be transmitted back to the studio or newsroom, the DCS had a resolution of 1.3 megapixels. The DCS 100 was publicly presented for the first time in Arles (France), at the Journées de l'Image Pro by Mr Ray H. DeMoulin, the worldwide President of the Eastman Kodak Company. 453 international journalists attended this presentation, which took place in the Palais des Congres of Arles. The predecessor to the commercial Digital Still Camera (DCS) was prototyped in the spring of 1987 at Kodak Research Labs. A 1.3 megapixel imager had been p ...

35 Mm Format
135 film, more popularly referred to as 35 mm film or 35 mm, is a format of photographic film used for still photography. It is a film with a film gauge of loaded into a standardized type of magazine – also referred to as a cassette or cartridge – for use in 135 film cameras. The engineering standard for this film is controlled by ISO 1007 titled '135-size film and magazine'. The term 135 was introduced by Kodak in 1934 as a designation for 35 mm film specifically for still photography, perforated with Kodak Standard perforations. It quickly grew in popularity, surpassing 120 film by the late 1960s to become the most popular photographic film size. Despite competition from formats such as 828, 126, 110, and APS, it remains the most popular film size today. The size of the 135 film frame with its aspect ratio of 1:1.50 has been adopted by many high-end digital single-lens reflex and digital mirrorless cameras, commonly referred to as " full frame".

Normal Lens
In photography and cinematography, a normal lens is a lens that reproduces a field of view that appears "natural" to a human observer. In contrast, depth compression and expansion with shorter or longer focal lengths introduces noticeable, and sometimes disturbing, distortion. The problem Photographic technology employs different physical methods from the human eye in order to capture images. Thus, manufacturing optics which produce images that appear natural to human vision is problematic. The eye has a nominal focal length of approximately 17mm, but it varies with accommodation. The nature of human binocular vision, which uses two lenses instead of a single one, and post-processing by the cortex is very different from the process of making and rendering a photograph, video or film. The structure of the human eye has a concave retina, rather than a flat sensor. This produces effects observed by Abraham Bosse, who in his 1665 illustration 'To prove that one can neither define ...

Angle Of View
The angle of view is the decisive variable for the visual perception of the size or projection of the size of an object. Angle of view and perception of size The perceived size of an object depends on the size of the image projected onto the retina. The size of the image depends on the angle of vision. A near and a far object can appear the same size if their edges produce the same angle of vision. With an optical device such as glasses or binoculars, microscope and telescope the angle of vision can be widened so that the object appears larger, which is favourable for the resolving power of the eye (see visual angle). Angle of view in photography In photography, angle of view (AOV) describes the angular extent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view. It is important to distinguish the angle of view from the angle of coverage, which describes the angle range that a lens can image. Typically the image ...

Focal Length
The focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system's optical power. A positive focal length indicates that a system converges light, while a negative focal length indicates that the system diverges light. A system with a shorter focal length bends the rays more sharply, bringing them to a focus in a shorter distance or diverging them more quickly. For the special case of a thin lens in air, a positive focal length is the distance over which initially collimated (parallel) rays are brought to a focus, or alternatively a negative focal length indicates how far in front of the lens a point source must be located to form a collimated beam. For more general optical systems, the focal length has no intuitive meaning; it is simply the inverse of the system's optical power. In most photography and all telescopy, where the subject is essentially infinitely far away, longer focal length (lower opti ...

Serial Cable
A serial cable is a cable used to transfer information between two devices using a serial communication protocol. The form of connectors depends on the particular serial port used. A cable wired for connecting two DTEs directly is known as a null modem cable. Maximum cable lengths The maximum working length of a cable varies depending on the characteristics of the transmitters and receivers, the baud rate on the cable, and the capacitance and electrical impedance of the cable. The RS-232 standard states that a compliant port must provide defined signal characteristics for a capacitive load of pF. This does not correspond to a fixed length of cable since varying cables have different characteristics. Empirically tested combinations of bit rate, serial ports, cable type, and lengths may provide reliable communications, but generally RS-232-compatible ports are intended to be connected by, at the most, a few tens of metres of cable. Other serial communications standards are better a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apple Macintosh
The Mac (known as Macintosh until 1999) is a family of personal computers designed and marketed by Apple Inc. Macs are known for their ease of use and minimalist designs, and are popular among students, creative professionals, and software engineers. The current lineup includes the MacBook Air and MacBook Pro laptops, as well as the iMac, Mac Mini, Mac Studio and Mac Pro desktops. Macs run the macOS operating system. The first Mac was released in 1984, and was advertised with the highly-acclaimed "1984" ad. After a period of initial success, the Mac languished in the 1990s, until co-founder Steve Jobs returned to Apple in 1997. Jobs oversaw the release of many successful products, unveiled the modern Mac OS X, completed the 2005-06 Intel transition, and brought features from the iPhone back to the Mac. During Tim Cook's tenure as CEO, the Mac underwent a period of neglect, but was later reinvigorated with the introduction of popular high-end Macs and the ongoing Apple s ...

Photo Marketing Association
The Photo Marketing Association International (PMA) International Convention and Trade Show was an annual imaging technology trade show conducted by PMA held in Las Vegas. Since 2012, the show has been branded as PMA@CES, reflecting its rescheduling to coincide with the Consumer Electronics Show, a major annual consumer electronics trade show also held in Las Vegas. The PMA International Convention and Trade Show is frequently the occasion for the public introduction of important imaging products. The major competition for this trade show is Photokina, held in even-numbered years in Cologne, Germany. In 2012, PMA announced it would launch an online community known as The Big Photo Show, with associated trade shows under that banner in the U.S. The first such show was held in Los Angeles Los Angeles ( ; es, Los Ángeles, link=no , ), often referred to by its initials L.A., is the largest city in the state of California and the second most populous city in the United States ...

Macworld/iWorld
Macworld/iWorld was an information technology trade show with conference tracks dedicated to the Apple Macintosh platform. It was held annually in the United States during January. Originally ''Macworld Expo'' and then ''Macworld Conference & Exposition'', the gathering dates back to 1985. The conference was organized by International Data Group (IDG), co-publisher of ''Macworld'' magazine. On December 18, 2008, Apple announced that the 2009 Macworld Conference & Expo would be the last in which the company participates. On October 14, 2014, IDG suspended Macworld/iWorld indefinitely. History The first Macworld Expo occurred in 1985 in San Francisco. The conference itself was created by Peggy Kilburn, who helped to increase the size and profit of the event during her tenure (1985–1999). Among the speakers recruited by Kilburn were David Pogue, Steve Case, Bob LeVitus, as well as representatives from BMUG, LaserBoard, and other major user groups. Participation by Apple was us ...
