Speedlight
Speedlight is the brand name used by Nikon Corporation for their photographic flash units, used since the company's introduction of strobe flashes in the 1960s. Nikon's standalone Speedlights (those not built into the company's cameras) have the ''SB-'' prefix as part of their model designation. Current Speedlights and other Nikon accessories make up part of Nikon's ''Creative Lighting System'' (CLS), which includes the ''Advanced Wireless Lighting'', that enables various Nikon cameras to control multiple Nikon flash units in up to three separate controlled groups by sending encoded pre-flash signals to slave units. Nikon's competitors like Canon and Ricoh use the similar name Speedlite for their flashes. Both names indicate that strobe flashes produce much shorter and more intense bursts of light than earlier photographic lighting systems, such as flashbulbs, or continuous lamps used in some studio situations. Models Nikon's Speedlight units are: (Update September 15, 2014) * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guide Number
When setting Flash (photography), photoflash Exposure (photography), exposures, the guide number (GN) of photoflash devices (flashbulbs and electronic devices known as "studio strobes", "on-camera flashes", "electronic flashes", "flashes", "speedlights", and "speedlites") is a measure photographers can use to calculate either the required f-number, f-stop for any given flash-to-subject distance, or the required distance for any given f-stop. To solve for either of these two variables, one merely divides a device's guide number by the other. Though guide numbers are influenced by a variety of variables, their values are presented as the product of only two factors as follows: ::Guide number = f-number × distance This simple inverse relationship holds true because the brightness of a flash declines with the square of the distance, but the amount of light admitted through an aperture decreases with the square of the f-number.Scantips.com: Understanding Flash Guide Numbers, plus GN ...

Nikon D80
The Nikon D80 is a digital single-lens reflex camera model announced by Nikon on August 9, 2006. The camera shipped the first week of September to US retailers. Considered by many to be a hybrid of design elements of the entry-level D50 and high-end D200 cameras, it occupied the same price bracket the Nikon D70 did at the time of its release. It was replaced by the Nikon D90 in August 2008. Features * 10.2 Megapixel CCD sensor * Seven preset scene modes (Auto, Portrait, Landscape, Macro, Sports, Night Landscape and Night Portrait) selectable using a top-mounted dial * User-selectable image optimization options (Normal, Softer, Vivid, More vivid, Portrait, Custom and Black-and-white) * In-camera Retouch feature with D-Lighting, Red-eye correction, Trim, Image overlay, Monochrome and Filter effects * In-camera Multiple exposure feature (merges up to three consecutive images) * USB 2.0 Hi-speed interface * Pentaprism viewfinder, rather than the more compact penta-mirror set up ...

Nikon D40
The Nikon D40 is a 6.1-megapixel DX format DSLR Nikon F-mount camera announced by Nikon on November 16, 2006. It replaces the D50 as Nikon's entry level DSLR. It features a 2.5-inch 230,000-dot resolution LCD monitor, CCD sensor with ISO 200-1600 (3200 Hi-1) and 3D Color Matrix Metering. The D40 was the first Nikon DSLR without an in-body focus motor. Autofocus requires the use of a lens with an integrated autofocus-motor. In March 2007, Nikon released a sister model, the D40x, which included a 10.2-megapixel sensor and several other changes over the original D40. Features * 6.1-megapixel Nikon DX format CCD Sensor * 23.7 mm x 15.6 mm sensor size * SD and SDHC memory card file storage * ISO 200-1600. Hi-1 (ISO 3200) * 2.5-inch color LCD monitor with 3 colorful display options * File formats: JPEG, NEF (Nikon's RAW, 12-bit compressed * Nikon F-mount lenses * 3-area auto focus * Image assist * Fires continuously at a speed of up to 2.5 frames per second * EN-EL9 Lithium-i ...

Nikon D2H
The Nikon D2H is a professional-grade digital single-lens reflex camera introduced by Nikon Corporation on July 22, 2003. It uses Nikon's own JFET- LBCAST sensor with a 4.1-megapixel resolution, and is optimised for sports and action shooting that require a high frame rate. In 2005, the D2H was replaced by the D2Hs, which added new features derived from the 12-megapixel D2X digital SLR. The D2Hs was discontinued after the introduction of the D300 and D3 models. Like most early Nikon Digital SLR cameras, it uses a " DX Format" sensor, which applies a crop factor compared to 35 mm film of approximately 1.5×. D2Hs The D2Hs was announced on February 16, 2005, adding several improvements to the D2H design, although with the same sensor and body. Nikon added an improved light metering system, faster subject acquisition and tracking algorithms to the Multi-CAM-2000 Autofocus module, and expanded both the JPEG and RAW continuous shooting buffer. Nikon also reported impro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nikon D3
The Nikon D3 is a 12.0-megapixel professional-grade full frame (35 mm) digital single lens reflex camera (DSLR) announced by the Nikon Corporation on 23 August 2007 along with the Nikon D300 DX format camera. It was Nikon's first full-frame DSLR. The D3, along with the Nikon D3X, was a flagship model in Nikon's line of DSLRs, superseding the D2Hs and D2Xs. It was replaced by the D3S as Nikon's flagship DSLR. The D3, D3X, D3S, D4, D4s, D5, D6, D700, D800, D800Е and Df are the only Nikon FX format DSLRs manufactured in Japan. The D3S was replaced by the D4 in 2012. Technology The D3 features a full-frame 35 mm equivalent CMOS image sensor measuring 23.9 mm × 36.0 mm. This sensor is larger than the DX format sensors of all previous Nikon DSLRs, and Nikon has coined the term " FX format" to describe it. While the D3's sensor has larger pixels than some previous DX sensors, some previous DX sensors have larger pixels. The design of the D3's CMOS ...

Nikon D2X
The Nikon D2X is a 12.4-megapixel professional digital single-lens reflex camera (DSLR) that Nikon Corporation announced on September 16, 2004. The D2X was the high-resolution flagship in Nikon's DSLR line until June 2006 when it was supplanted by the D2Xs and, in time, the Nikon D3 range, Nikon D4 range, the Nikon D5 and the Nikon D6— the latter four using a FX full-format sensor. Technology The D2X uses a DX-format CMOS sensor supplied by Sony instead of either a charge-coupled device or the Nikon proprietary LBCAST sensor which had both dominated Nikon's digital SLR lineup until the D2X. The camera supports the sYCC color space. The CMOS sensor used in the D2X has the ability to resolve about nine times more than the human eye. At 90 line pairs/millimeter (90 lp/mm), the sensor can resolve extremely fine detail. This makes the camera perform exceptionally well when used as a landscape or scenic imager, since it can better resolve smaller detail in distant objects ...
