Canon EOS D60
The Canon EOS D60 is a discontinued 6.3 megapixel digital single lens reflex (DSLR) camera body, announced by Canon on February 22, 2002. It is part of the Canon EOS range, and accepts Canon EF, TS-E and MP-E lenses, but not Canon's later digital-only EF-S lens range. The EOS D60 sits in the prosumer (professional-consumer) line of digital SLR cameras. It succeeded the three megapixel EOS D30 and was replaced by the improved, six megapixel EOS 10D. In America, its initial pricing was US$1,999 for the basic body, or US$2,199 including battery, charger, and DC kit. Features The EOS D60 features: * 22.7 x 15.1 mm CMOS sensor (APS-C) * 6.3 megapixel effective (6.3 megapixel total) * Max resolution 3072 x 2048 * FOV crop (1.6x) * Canon EF lens mount (excludes EF-S) * 3-point auto focus * 100, 200, 400, 800, 1000 ISO speed equivalent * 30 to 1/4000 s shutter speed and bulb * TTL 35 zone SPC metering: evaluative, center weighted, partial * Exposure compensation -2 EV to ...

Canon EOS 60D
The Canon EOS 60D is an 18.1 megapixels semi-pro digital single-lens reflex camera made by Canon. It was announced on August 26, 2010, with a suggested retail price of US$1099.00. As a part of the Canon EOS two-digit line, it is the successor of the EOS 50D and is the predecessor of the EOS 70D. It is the first camera which has an articulating LCD screen. Apart from its screen, the main new features of the 60D in the two-digit Canon line include increased resolution and ISO range, full-HD video capabilities, and in-camera post-processing functions for the images. It uses the DIGIC 4 image processor. Like the 50D, the camera has an LCD of settings on the top of the camera where the ISO, AF-Mode, Shooting mode, and metering mode can be controlled. The 60D was offered for purchase as a body alone or in a package with an EF-S 18-200mm f/3.5-5.6 IS lens, EF-S 17–85mm f/4-5.6 IS USM lens, EF-S 18–135mm f/3.5-5.6 IS lens, EF-S 17-55mm f/2.8 IS USM lens, or an EF-S 18� ...

Canon EOS 10D
The Canon EOS 10D is a discontinued 6.3-megapixel semi-professional digital SLR camera, initially announced on 27 February 2003. It replaced the EOS D60, which is also a 6.3-megapixel digital SLR camera. It was succeeded by the EOS 20D in August 2004. Despite having an APS-C sensor, the 10D was introduced before EF-S lenses became available and was incompatible with them. The 10D is compatible only with EF lenses. All successive Canon Digital SLR cameras with APS-C sensors can mount EF-S lenses. The 10D captured RAW images in the Canon CRW file format, which was retired by Canon, although modern versions of Canon's Digital Photo Professional will read it. When it was released, recommended retail price in the USA was $1,999 (£1,520). Compared to the D60 While the 10D shared some similarities with the D60—both used sensors of roughly the same resolution, both used the EF lens mount and BG-ED3 battery grip—the 10D saw many major changes.

Gram
The gram (originally gramme; SI unit symbol g) is a Physical unit, unit of mass in the International System of Units (SI) equal to one thousandth of a kilogram. Originally defined in 1795 as "the absolute Mass versus weight, weight of a volume of pure water equal to Cube (algebra), the cube of the hundredth part of a metre [1 Cubic centimetre, cm3], and at Melting point of water, the temperature of Melting point, melting ice", the defining temperature (0 °C) was later changed to the temperature of maximum density of water (approximately 4 °C). Subsequent redefinitions agree with this original definition to within 30 Parts-per notation, parts per million (0.003%), with the maximum density of water remaining very close to 1 g/cm3, as shown by modern measurements. By the late 19th century, there was an effort to make the Base unit (measurement), base unit the kilogram and the gram a derived unit. In 1960, the new International System of Units defined a '' ...

E-TTL
Canon's EOS flash system refers to the photographic flash equipment and automation algorithms used on Canon's film (35mm and APS) or digital EOS single-lens reflex cameras. The line was first introduced in 1987. It has gone through a number of revisions over the years, as new flash exposure metering systems have been introduced. The main light-metering technologies are known as A-TTL, E-TTL, and E-TTL II. The EOS flash system is capable of wireless multiple flash control, whereby a master flash unit IR ( ST-E2) or RF ( ST-E3-RT) transmitter mounted on the camera body can control up to 3 (optical) or 5 (radio) groups of flash units. The Canon EOS 7D The Canon EOS 7D is a high-end APS-C digital single-lens reflex camera made by Canon. It was announced on 1 September 2009 with a suggested retail price of US$1,699, and was marketed as a semi-professional DSLR camera. Among its features are a ... is the first Canon body to be able to control Speedlites wirelessly without the use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Balance
In photography and image processing, color balance is the global adjustment of the intensities of the colors (typically red, green, and blue primary colors). An important goal of this adjustment is to render specific colors – particularly neutral colors like white or grey – correctly. Hence, the general method is sometimes called gray balance, neutral balance, or white balance. Color balance changes the overall mixture of colors in an image and is used for color correction. Generalized versions of color balance are used to correct colors other than neutrals or to deliberately change them for effect. White balance is one of the most common kinds of balancing, and is when colors are adjusted to make a white object (such as a piece of paper or a wall) appear white and not a shade of any other colour. Image data acquired by sensors – either film or electronic image sensors – must be transformed from the acquired values to new values that are appropriate for color reproduct ...

Through The Lens
In photography, through-the-lens metering (TTL metering) refers to a feature of cameras whereby the intensity of light reflected from the scene is measured through the lens; as opposed to using a separate metering window or external hand-held light meter. In some cameras various TTL metering modes can be selected. This information can then be used to set the optimal film or image sensor exposure ( average luminance), it can also be used to control the amount of light emitted by a flash unit connected to the camera. Description Through-the-lens metering is most often associated with single-lens reflex (SLR) cameras. In most film and digital SLRs, the light sensor(s) for exposure metering are incorporated into the pentaprism or pentamirror, the mechanism by which a SLR allows the viewfinder to see directly through the lens. As the mirror is flipped up, no light can reach there during exposure, the necessary amount of exposure needs to be determined before the actual exposure. Cons ...

Prosumer
A prosumer is an individual who both consumes and produces. The term is a portmanteau of the words '' producer'' and ''consumer''. Research has identified six types of prosumers: DIY prosumers, self-service prosumers, customizing prosumers, collaborative prosumers, monetised prosumers, and economic prosumers. The terms ''prosumer'' and ''prosumption'' were coined in 1980 by Alvin Toffler, an American futurist, and were widely used by many technology writers of the time. Technological breakthroughs and a rise in user participation blurs the line between production and consumption activities, with the consumer becoming a prosumer. Definitions and contexts Prosumers have been defined as "individuals who consume and produce value, either for self-consumption or consumption by others, and can receive implicit or explicit incentives from organizations involved in the exchange." The term has since come to refer to a person using commons-based peer production. In the digital and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canon EF-S Lens Mount
The Canon EF-S lens mount is a derivative of the EF lens mount created for some Canon digital single-lens reflex cameras with APS-C sized image sensors. It was released in 2003. Cameras with the EF-S mount are backward compatible with the EF lenses and, as such, have a flange focal distance of 44.0 mm. Such cameras, however, have more clearance, allowing lens elements to be closer to the sensor than in the EF mount. Only Canon cameras released after 2003 with APS-C sized sensors support the EF-S mount. The "S" in EF-S has variously been described by Canon as coming from either "Small image circle" (the lens projects a smaller image circle than normal EF lenses to match the sensor), or "Short back focus" (the smaller mirror used in APS-C cameras also allows optical elements to protrude further into the camera body, reducing the minimum distance between the sensor and the back element of the lens). The combination of a smaller sensor and shorter back focal length distance en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Digital Single Lens Reflex
A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that combines the optics and mechanisms of a single-lens reflex camera with a solid-state image sensor and digitally records the images from the 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 optical 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 intercha ...

Megapixel
In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a Raster graphics, raster image, or the smallest addressable element in a dot matrix display device. In most digital display devices, pixels are the smallest element that can be manipulated through software. Each pixel is a Sampling (signal processing), sample of an original image; more samples typically provide more accurate representations of the original. The Intensity (physics), intensity of each pixel is variable. In color imaging systems, a color is typically represented by three or four component intensities such as RGB color model, red, green, and blue, or CMYK color model, cyan, magenta, yellow, and black. In some contexts (such as descriptions of camera sensors), ''pixel'' refers to a single scalar element of a multi-component representation (called a ''photosite'' in the camera sensor context, although ''wikt:sensel, sensel'' is sometimes used), while in yet ...
