Nikon COOLPIX L830 review The Nikon Coolpix L830 represents the new pinnacle of Nikon’s budget-conscious, easy to use Coolpix L-series. Considering its relatively attractive price of £229.99 / $299.95 / €279, you get a lot of bang for your buck. Headline specs are its 34x zoom lens, giving a very useful focal length range of 22.5-765mm (in 35mm camera terms). To ensure sharp shots at such long focal lengths, the L830 also utilises Nikon’s Hybrid Vibration Reduction system. At the heart of the camera is a 16.0-megapixel CMOS sensor capable of a maximum ISO3200 sensitivity and Full HD video capture. Externally the most notable new feature is a high-resolution, 921k-dot monitor which can be tilted up and down. The Nikon Coolpix L830 also follows the L-series trend of being powered by AA batteries. The Nikon COOLPIX L830 is a budget bridge super-zoom. Its DSLR-styled body is light and compact - a step down in scale from the mid and higher end P-range super-zooms. Launched in Janua...

Canon is bringing its latest mirrorless camera, the EOS M3, to the US after all. The Japan-based manufacturer announced this compact shooter back in February, but now people in the States will have a chance to get their hands on it. A follow-up to the M2 from 2013, the M3 features a 24.2-megapixel APS-C CMOS sensor, Hybrid AF III focusing system and Digic 6 image processor -- all specs found on the Rebel T6s and T6i DSLRs. Just as well, Canon's new mirrorless comes with the same battery type (LP-E17), focus peaking and dynamic stabilization as its bigger siblings, so you can expect similar performance from a camera that's wrapped in a much smaller package. What's more, you'll get NFC, WiFi and 1080p recording at 24, 25 and 30 fps, while the max ISO range is set at 6,400 and 12,800 for video and pictures, respectively. The EOS M3 is Canon's third mirrorless camera, following the M2 and the original M. Announced in February 2015 (13 months a...

The single-lens reflex camera uses an automatic moving mirror system which allows the photographer to see exactly what will be captured by the film, as opposed to non-SLR cameras where the view through the viewfinder could be significantly different from what was captured on film. SLR cameras let direct viewing through the lens, using a pentaprism situated above the lens optical path. So, the image the camera lens sees is reflected by the automatic moving mirror, which in turn projects the image upward to the pentaprism; finally, the pentaprism further reflects this image which we see through the camera eyepiece. The first Single Lense Reflex camera was the Ihagee Exakta which was introduced in 1933. It was a compact SLR which used 127 rollfilm. Although world's first true 35mm SLR was Soviet Sport camera from 1935, the first Western SLR to use 35mm film was the German Kine Exakta that came to the market in 1936. After World War II, as 35mm SLR design gained popularity, there was...

Victor Hasselblad AB is a Swedish firm which produces medium-format cameras and photographic equipment based in Gothenburg, Sweden. The company is best known for the medium-format cameras which has been manufactured since World War II. The most famous use of the Hasselblad camera was during the Apollo Program missions when man first landed on the Moon. Almost all of the still photographs taken during these missions used specially modified Hasselblad cameras. Hasselblad's traditional V-System cameras are still widely used by professional and serious amateur photographers. One reason is a reputation for long service life and quality of available lenses. Their newer H-System cameras produced in cooperation with Fuji are market leaders, competing with Sinar, Mamiya and others in the medium format digital camera market. The company was established in 1841 in Gothenburg, Sweden, as a trading company, F. W. Hasselblad and Co. The founder's son, Arvid Viktor Hasselblad, was interested...

Photography is the process, activity and art of creating still pictures by recording light patterns reflected or emitted from objects on a sensitive medium such as a chemical or electronic sensor during a timed exposure, usually through a photographic lens in a device known as a camera that also stores the resulting information chemically or electronically. But from a journalist or historian point of view, photography is the process of documenting reality by recording visual fragments of historical events. Photography has many uses for business, science, art and pleasure. Etymologically, the word “photography” derives from two Greek roots; photo, light; graph, drawn. At the beginning, in ancient times, was the Camera Oscura; a darkened room used to form inverted images on one wall through a small hole in the oposite. Such a principle was known by ancient Greek thinkers. In the 16th century, the clarity of the image was improved and enhanced in Italy by fixing a convex lens in the hole...

Medium format is a film format used in still photography and the related cameras and equipment that use this film. Generally, the term applies to film and cameras used to produce images larger than the 24 by 36 mm of 135 film, but smaller than the 4”×5” size, which is considered to be large format. Although at one time or another a variety of medium format film sizes were manufactured, today the vast majority of medium format film is produced in the 6 cm 120 and 220 sizes. Other sizes are mainly produced for use in antique cameras, and many people assume 120/220 film when the term medium format is used. Medium format photography uses a larger film type than 35mm film cameras, allowing for more detail to be captured and the negative to be printed dramatically larger than 35mm film prints. Medium format has moved from being the most widely used film size (1890s through 1950s) to a niche used by many professionals and some amateur enthusiasts, but one which is still substantially more po...

A photographic camera basically works like the human eye . The Camera has a body, formerly known as “camara oscura”, so the human eye, which is simply called eye ball. Like a camera body, it is dark inside and has a layer of sensitive cells lining the eye ball inner wall. This layer of sensitive cells is known as retina, which can be likened to the film in a film camera. Yes, a camera has a lens, or set of lenses, that one replaces depending on how far the object you want to take a picture of is. So the human eye also has a lens, which is held in place by the ciliary muscle. When this tiny muscle contracts change the shape of the lens, as when you change the focus of your attention from a near object to a distant one. The image is focused upside down on the photographic film, which is later developed and printed on paper. So, the images of reality we see daily are focused upside down, too, on our retina. The pictures are then transmitted through the optic nerve to our brain where we a...
