Mamiya
is a Japanese company that manufactures high-end cameras and other related photographic and optical equipment. With headquarters in Tokyo, it has two manufacturing plants and a workforce of over 200 people. The company was founded in May 1940 by camera designer Seiichi Mamiya () and financial backer Tsunejiro Sugawara. History Mamiya originally achieved fame for its professional medium-format film cameras such as the Mamiya Six and the Mamiya Press series. It later developed the industry workhorse RB67 series, the RZ67, the 645 and the twin-lens reflex Mamiya C-series, used by advanced amateur and professional photographers. Many Mamiya models over the past six decades have become collectors' items. The earliest Mamiya Six medium-format folding camera, the 35 mm Mamiya-Sekor 1000DTL, the lightweight 35 mm Mamiya NC1000, the 6×6 cm medium-format C series of interchangeable-lens twin-lens reflex (TLR) cameras, and the press cameras of the Super/Universal seri ...

Camera Lens
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. There is no major difference in principle between a lens used for a still camera, a video camera, a telescope, a microscope, or other apparatus, but the details of design and construction are different. A lens might be permanently fixed to a camera, or it might be interchangeable with lenses of different focal lengths, apertures, and other properties. While in principle a simple convex lens will suffice, in practice a compound lens made up of a number of optical lens elements is required to correct (as much as possible) the many optical aberrations that arise. Some aberrations will be present in any lens system. It is the job of the lens designer to balance these and produce a d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bliss (image)
''Bliss'', originally titled Bucolic Green Hills, is the default computer wallpaper of Microsoft's Windows XP operating system. It is a virtually unedited photograph of a green hill and blue sky with clouds in the Los Carneros American Viticultural Area of California's Wine Country. Charles O'Rear took the photo in January 1996 and Microsoft bought the rights in 2000. It is estimated that billions of people have seen the picture, possibly making it the most viewed photograph in history. Overview Former ''National Geographic'' photographer Charles O'Rear, a resident of the nearby Napa Valley, took the photo on film with a medium-format Mamiya RZ67 camera while on his way to visit his girlfriend in 1996. While it was widely believed later that the image was manipulated or even created with software such as Adobe Photoshop, O'Rear says it never was. He sold it to Westlight for use as a stock photo titled ''Bucolic Green Hills''.Metadata of Bliss, Windows XP Beta 2 Westlight ...

Mamiya RB67
The Mamiya RB67 is a professional medium format single-lens reflex system camera manufactured by Mamiya. There are three successive models: the RB67 Professional (released in 1970), RB67 Pro-S (released in 1974) and RB67 Pro-SD (released in 1990). It is primarily designed for studio use, but can also be used in the field. Details The RB67 Professional was introduced in 1970 with a similar look to conventional medium format SLR cameras like the Hasselblad, but was larger due to the 6×7 cm frame format, closer to the typical 8×10 inch aspect ratio of portraits. However, the RB67 differed visually from other 6x7 cameras of the time, which resembled very large 35 mm cameras. There are three successive models: the RB67 Professional (first model released in 1970), RB67 Pro-S (released in 1974) and RB67 Pro-SD (released in 1990). The RB67 is a modular camera system, meaning lenses, viewfinders, ground glasses, film winders and film backs are all interchangeable. It is primarily design ...

Bayonet-mount
A bayonet mount (mainly as a method of mechanical attachment, such as fitting a lens to a camera using a matching lens mount) or bayonet connector (for electrical use) is a fastening mechanism consisting of a cylindrical male side with one or more radial pins, and a female receptor with matching L-shaped slot(s) and with spring(s) to keep the two parts locked together. The slots are shaped like a capital letter L with serif (a short upward segment at the end of the horizontal arm); the pin slides into the vertical arm of the L, rotates across the horizontal arm, then is pushed slightly upwards into the short vertical "serif" by the spring; the connector is no longer free to rotate unless pushed down against the spring until the pin is out of the "serif". The bayonet mount is the standard light bulb fitting in the United Kingdom and in many countries that were members of the British Empire including Pakistan, Australia, Hong Kong, Fiji India, Sri Lanka, Ireland, and New ...

Exposure (photography)
In photography, exposure is the amount of light per unit area (the image plane's illuminance times the exposure time) reaching a frame of photographic film or the surface of an electronic image sensor, as determined by shutter speed, lens F-number, and scene luminance. Exposure is measured in lux seconds, and can be computed from exposure value (EV) and scene luminance in a specified region. An "exposure" is a single shutter cycle. For example, a long exposure refers to a single, long shutter cycle to gather enough dim light, whereas a multiple exposure involves a series of shutter cycles, effectively layering a series of photographs in one image. The accumulated ''photometric exposure'' (''H''v) is the same so long as the total exposure time is the same. Definitions Radiant exposure Radiant exposure of a ''surface'', denoted ''H''e ("e" for "energetic", to avoid confusion with photometric quantities) and measured in , is given by :H_\mathrm = E_\mathrmt, where *''E ...

Windows XP
Windows XP is a major release of Microsoft's Windows NT operating system. It was released to manufacturing on August 24, 2001, and later to retail on October 25, 2001. It is a direct upgrade to its predecessors, Windows 2000 for high-end and business users and Windows Me for home users, available for any devices running Windows NT 4.0, Windows 98, Windows 2000 and Windows Me that meet the new Windows XP system requirements. Development of Windows XP began in the late 1990s under the codename "Neptune", built on the Windows NT kernel explicitly intended for mainstream consumer use. An updated version of Windows 2000 was also initially planned for the business market. However, in January 2000, both projects were scrapped in favor of a single OS codenamed "Whistler", which would serve as a single platform for both consumer and business markets. As a result, Windows XP is the first consumer edition of Windows not based on the Windows 95 kernel and MS-DOS. Windows XP removed supp ...

Single-lens Reflex Camera
A single-lens reflex camera (SLR) is a camera that typically uses a mirror and prism system (hence "reflex" from the mirror's reflection) that permits the photographer to view through the lens and see exactly what will be captured. With twin lens reflex and rangefinder cameras, the viewed image could be significantly different from the final image. When the shutter button is pressed on most SLRs, the mirror flips out of the light path, allowing light to pass through to the light receptor and the image to be captured.

Depth Of Field
The depth of field (DOF) is the distance between the nearest and the furthest objects that are in acceptably sharp focus in an image captured with a camera. Factors affecting depth of field For cameras that can only focus on one object distance at a time, depth of field is the distance between the nearest and the farthest objects that are in acceptably sharp focus. "Acceptably sharp focus" is defined using a property called the " circle of confusion". The depth of field can be determined by focal length, distance to subject, the acceptable circle of confusion size, and aperture. Limitations of depth of field can sometimes be overcome with various techniques and equipment. The approximate depth of field can be given by: : \text \approx \frac for a given circle of confusion (c), focal length (f), f-number (N), and distance to subject (u). As distance or the size of the acceptable circle of confusion increases, the depth of field increases; however, increasing the size ...
