Canon PowerShot S90
The Canon PowerShot S90 is a high-end 10.0-megapixel compact digital camera originally announced in 2009. The PowerShot S90 is the successor of the Canon PowerShot S80. The almost 4-year gap between the S80 and the S90, compared with intervals of 6 months to 1 year between prior versions, led to the line being popularly considered discontinued, and thus the S90 as a revival, rather than a strict successor. Features * 10.0 megapixels * JPEG (Exif 2.2) support * Raw image file format; one of few "point and shoot" cameras to have raw formatting. (Note: Raw format is not available in Auto, Low Light, and SCN modes. Raw is available in Program, TV (shutter priority), Av (aperture priority), Manual, and Custom modes) * ISO sensitivity 80–3200 and auto. Low light mode can shoot up to ISO 12800. * Wide-angle zoom lens 6.0–22.5 mm (35 mm equivalent: 28–105 mm) * Full manual control * Customizable Control Ring to control ISO, shutter speed, aperture, focus, or exposur ...

Raw Image Format
A camera raw image file contains unprocessed or minimally processed data from the image sensor of either a digital camera, a motion picture film scanner, or other image scanner. Raw files are named so because they are not yet processed and therefore are not ready to be Photographic printing, printed, viewed or edited with a bitmap graphics editor. Normally, the image is processed by a raw converter in a wide-gamut internal color space where precise adjustments can be made before file format conversion, conversion to a viewable file format such as JPEG or PNG for storage, printing, or further manipulation. There are dozens of raw formats in use by different manufacturers of digital image capture equipment. Rationale Raw image files are sometimes incorrectly described as "digital Negative (photography), negatives", but neither are they negatives nor do the unprocessed files constitute visible images. Rather, the Raw datasets are more like Exposure (photography), exposed but Lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olympus PEN E-P2
The Olympus Pen E-P2 announced on 5 November 2009 is Olympus Corporation's second camera that adheres to the Micro Four Thirds (MFT) system design standard. The E-P2 succeeds the Olympus Pen E-P1 a little over five months after the introduction of the EP-1. Features The EP-2 addresses some of the concerns that critics had about the EP-1: slow autofocus speed and difficulty seeing the LCD panel under certain (e.g., bright, sunny) conditions. The autofocus speed was addressed with a firmware update, and the introduction of new lenses, although critically, the autofocus speed does not improve much with the originally issued 14–42 mm ƒ/3.5–5.6 kit zoom lens (28–90 mm equivalent), or the 17 mm ƒ/2.8 (34 mm equivalent) pancake lens. The EP-2 added an Accessory Port, a power and communication port, which allowed the use of various accessories, such as an external stereo microphone for HD video recording. However, the principal use of the accessory port wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olympus PEN E-P1
The Olympus Pen E-P1 announced on 16 June 2009 is Olympus Corporation's first camera that adheres to the Micro Four Thirds (MFT) system design standard. The first camera to use the Micro Four Thirds mount was Panasonic's G-1 camera. Features The design of the camera is reminiscent of the Olympus Pen half frame film cameras and is marketed as the Olympus digital PEN. The model presented on 16 June 2009 was very similar in looks to the Olympus Pen F. Initially, two micro 4/3 lenses were available from Olympus, one 14–42 mm f/3.5–5.6 zoom and a 17 mm f/2.8 pancake prime lens. Remarkably, with the exception of the optical viewfinder, the E-P1 seemed to fit most of the features found on the Olympus E-620, a larger Four Thirds system DSLR, into the small, compact MFT form factor. In addition to Micro Four Thirds lenses, Olympus offers adapters allowing the use of Four Thirds lenses, or OM Zuiko lenses originally manufactured for use on the classic OM series of film S ...

Panasonic Lumix DMC-GF1
Panasonic Lumix DMC-GF1 was introduced in September 2009 as the third camera in Panasonic's Lumix G-series, using the Micro Four Thirds system. It was the first model in the "GF" line, which is primarily distinguished from the other Lumix G cameras by the lack of an integrated electronic viewfinder. Features The design of the DMC-GF1 is similar to that of the Olympus E-P1 which was introduced a few months earlier. The GF1 is 35% smaller than earlier G models. It has the same 12.1 megapixel sensor as the DMC-G1, 1280 × 720 HD recording in AVCHD Lite format, an optional hot-shoe mounted electronic viewfinder, and a 3-inch LCD with 460,000 dots. It was announced at the 2009 Internationale Funkausstellung Berlin consumer electronics exhibition. This model in the Lumix range was claimed by Panasonic as the world's smallest and lightest system digital camera with a built-in flash capability. Although the GF1 is small it still offers many advanced features ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mirrorless Interchangeable Lens Camera
A mirrorless camera is a photo camera featuring a single, removable lens and a digital display. The camera does not have a reflex mirror or optical viewfinder like a digital single-lens reflex (DSLR) camera, but may have an electronic viewfinder. Many mirrorless cameras retain a mechanical shutter. Like a DSLR, a mirrorless camera accepts any of a series of interchangeable lenses compatible with its lens mount. Terminology Mirrorless cameras are sometimes referred to as mirrorless interchangeable-lens cameras (MILC), or digital single-lens mirrorless (DSLM) cameras. This latter name highlights their connection to DSLRs. Other terms include electronic viewfinder interchangeable lens (EVIL) cameras and compact system cameras (CSCs). Overview Mirrorless cameras are mechanically simpler than DSLR cameras, and are smaller, lighter, and quieter due to the elimination of the moving mirror. While nearly all mirrorless cameras have a mechanical shutter, many also have an elect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Canon PowerShot S95
The Canon PowerShot S95 is a high-end 10.0-megapixel compact digital camera announced and released in 2010. It was designed as the successor to the Canon PowerShot S90 in the S series of the Canon PowerShot line of cameras. This model is considered high-end, professional, or prosumer because of its price, its feature set, and its high-sensitivity image sensor. Its 10-megapixel image sensor is larger than typical sensors found in point-and-shoot cameras. This, along with the advanced image stabilization system, allows for sharp images in lower light scenarios, at an ISO of up to 3,200. The S95 is similar to the S90, but adds a number of refinements. Among other things, it features a thinner body, improved image stabilization, an automated HDR shooting mode, 720p HD-quality video recording with stereo sound, and a more ergonomic finish and controls. Other features include a tracking autofocus function, enabling it to track and focus on moving subjects. Features * 10.0 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Canon PowerShot G
The Canon PowerShot G is a series of digital cameras introduced by Canon in its PowerShot line in 2000. The G series cameras are Canon's flagship compact models aimed at photography enthusiasts desiring more flexibility than a point-and-shoot without the bulk of a digital single-lens reflex camera. The G series has a lithium-ion battery, full manual exposure control, an articulated LCD screen (G7, G9, G10, G15, and G16 have a fixed screen), Raw image format capture (all models except G7), a lens with a wider maximum aperture than standard PowerShot models, remote capture (except G11), and faster image processing. The range also includes a hot shoe (except G7 X and G9 X) for an external flashgun, including Canon's EX range. New models in the series have larger sensors than most other point-and-shoot cameras ( G1X, G1X Mark II, G7X).

DIGIC
Digital Imaging Integrated Circuit (often styled as "DiG!C") is Canon Inc.'s name for a family of signal processing and control units for digital cameras and camcorders. DIGIC units are used as image processors by Canon in its own digital imaging products. Several generations of DIGICs exist, and are distinguished by a version number suffix. Currently, DIGIC is implemented as an application-specific integrated circuit (ASIC) designed to perform high speed signal processing as well as the control operations in the product in which it has been incorporated. Over its numerous generations, DIGIC has evolved from a system involving a number of discrete integrated circuits to a single chip system, many of which are based around the ARM instruction set. Custom firmware for these units has been developed to add features to the cameras. DIGIC in Cameras Original DIGIC The original DIGIC was used on the PowerShot G3 (Sep 2002), Canon S1 IS (Mar 2004), A520 (Mar 2005), and other came ...

Film Speed
Film speed is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system. A closely related ISO system is used to describe the relationship between exposure and output image lightness in digital cameras. Relatively insensitive film, with a correspondingly lower speed index, requires more exposure to light to produce the same image density as a more sensitive film, and is thus commonly termed a ''slow film''. Highly sensitive films are correspondingly termed ''fast films''. In both digital and film photography, the reduction of exposure corresponding to use of higher sensitivities generally leads to reduced image quality (via coarser film grain or higher image noise of other types). In short, the higher the sensitivity, the grainier the image will be. Ultimately sensitivity is limited by the quantum efficiency of the film or sensor. Film speed measurement systems His ...
