Full-frame DSLR
A full-frame DSLR is a digital single-lens reflex camera (DSLR) with a 35 mm image sensor format (). Historically, 35 mm was one of the standard film formats, alongside larger ones, such as medium format and large format. The full-frame DSLR is in contrast to full-frame mirrorless interchangeable-lens cameras, and DSLR and mirrorless cameras with smaller sensors (for instance, those with a size equivalent to APS-C-size film), much smaller than a full 35 mm frame. Many digital cameras, both compact and SLR models, use a smaller-than-35 mm frame as it is easier and cheaper to manufacture imaging sensors at a smaller size. Historically, the earliest digital SLR models, such as the Nikon NASA F4 or Kodak DCS 100, also used a smaller sensor. Kodak states that 35 mm film (note: in " Academy format", 21.0 mm × 15.2 mm) has the equivalent of 6K horizontal resolution, according to a senior vice president of IMAX. This equates to 10K horizontal resolution in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angénieux Retrofocus
The Angénieux retrofocus photographic lens is a wide-angle lens design that uses an inverted telephoto configuration. The popularity of this lens design made the name retrofocus synonymous with this type of lens. The Angénieux retrofocus for still cameras was introduced in France in 1950 by Pierre Angénieux. Inverted telephoto concept The telephoto lens configuration combines positive and negative lens groups with the positive at the front, so as to reduce the back focal distance of the lens (the distance between the back of the lens and the image plane) to a figure shorter than the focal length. This is for practical, not optical reasons, because it allows telephoto lenses to be made shorter and less cumbersome. The inverted telephoto configuration does the reverse, employing one or more negative lens groups at the front to increase the back focal distance of the lens – possibly to a figure greater than the focal length – in order to allow for additional optical ...

Canon EOS-1Ds Mark II
The EOS-1Ds Mark II is a digital SLR camera body introduced by Canon Inc. in 2004. It was the top model in the Canon EOS line of digital cameras until April 2007, with a full-frame 16.7 megapixel CMOS sensor. The EOS-1Ds Mark II had the highest pixel count available in a 35mm format digital SLR at the time of its introduction until its successor was announced in August 2007. It uses the EF lens mount. The EOS-1Ds Mark II is a professional grade camera body and is large, ruggedly built, and dust/weather-resistant. Being an autofocus camera, it has multiple autofocus modes and uses a 45-point autofocus system, and an option for manual focusing. Its viewfinder is a "fixed pentaprism". It also has a 2", TFT color LCD. Its dimensions are 156 mm in width, 157.6 mm in height, and 79.9 mm in depth (6.14 in × 6.20 in × 3.15 in). Its mass (without a battery) is . The camera's image sensor is a single-plate CMOS-based integrated circuit, 24 mm × 36 mm in s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canon EOS-1Ds
The EOS-1Ds is a full-frame 11.1-megapixel digital SLR camera body made by Canon in the 1Ds series, released on 24 September 2002. It was Canon's first full-frame DSLR. Its dimensions are 156 x 157.6 x 79.9 mm (6.1 x 6.2 x 3.1 in.) and mass (without a battery) is 1,265 g. The ~11 megapixel, full size 35mm digital camera was far ahead of other cameras counting usually much less megapixels, and having smaller size frame. The price was $7,999 in 2002 (). Functions Being an autofocus camera, it has two autofocus modes, and an option for manual focusing. Its viewfinder is a glass pentaprism. It also has a two-inch, thin-film transistor, color liquid-crystal monitor with approximately 120,000 pixels. The camera's image sensor is a CMOS-based integrated circuit with Bayer filters for RGB color detection (Canon calls it ''single-plate'', in contrast with three-CCD sensors). It has approximately 11.4 million effective pixels. A non-removable optical anti-aliasing filt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Photolithography
In integrated circuit manufacturing, photolithography or optical lithography is a general term used for techniques that use light to produce minutely patterned thin films of suitable materials over a substrate, such as a silicon wafer, to protect selected areas of it during subsequent etching, deposition, or implantation operations. Typically, ultraviolet light is used to transfer a geometric design from an optical mask to a light-sensitive chemical (photoresist) coated on the substrate. The photoresist either breaks down or hardens where it is exposed to light. The patterned film is then created by removing the softer parts of the coating with appropriate solvents. Conventional photoresists typically consists of three components: resin, sensitizer, and solvent. Photolithography processes can be classified according to the type of light used, such as ultraviolet, deep ultraviolet, extreme ultraviolet, or X-ray. The wavelength of light used determines the minimum feature si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semiconductor Device Fabrication
Semiconductor device fabrication is the process used to manufacture semiconductor devices, typically integrated circuit (IC) chips such as modern computer processors, microcontrollers, and memory chips such as NAND flash and DRAM that are present in everyday electrical and electronics, electronic devices. It is a multiple-step sequence of Photolithography, photolithographic and chemical processing steps (such as surface passivation, thermal oxidation, planar process, planar diffusion and p–n junction isolation, junction isolation) during which electronic circuits are gradually created on a wafer (electronics), wafer made of pure semiconducting material. Silicon is almost always used, but various compound semiconductors are used for specialized applications. The entire manufacturing process takes time, from start to packaged chips ready for shipment, at least six to eight weeks (tape-out only, not including the circuit design) and is performed in highly specialized semiconduct ...

Telephoto
A telephoto lens, in photography and cinematography, is a specific type of a long-focus lens in which the physical length of the lens is shorter than the focal length. This is achieved by incorporating a special lens group known as a ''telephoto group'' that extends the light path to create a long-focus lens in a much shorter overall design. The angle of view and other effects of long-focus lenses are the same for telephoto lenses of the same specified focal length. Long-focal-length lenses are often informally referred to as ''telephoto lenses'', although this is technically incorrect: a telephoto lens specifically incorporates the telephoto group. Telephoto lenses are sometimes broken into the further sub-types of short telephoto (85–135 mm in 35 mm film format), medium telephoto: (135–300 mm in 35 mm film format) and super telephoto (over 300 mm in 35 mm film format) . Construction In contrast to a telephoto lens, for any given focal lengt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Architectural Photography
Architectural photography is the sub genre of the photography discipline where the primary emphasis is made to capturing photographs of buildings and similar architectural structures that are both aesthetically pleasing and accurate in terms of representations of their subjects. Architectural photographers are usually skilled in the use of specialized techniques and cameras for producing such specialized photography. History The first permanent photograph, ''View from the Window at Le Gras'' by Nicéphore Niépce, was also the first architectural photograph as it was a view of buildings. Similarly, photographs taken by early photographer William Henry Fox Talbot were of architecture, including his photograph of a Latticed window in Lacock Abbey taken in 1835. Throughout the history of photography, architectural structures including buildings have been highly valued photographic subjects, mirroring society's appreciation for architecture and its cultural significance.
