A single-lens reflex camera (SLR) is a camera that typically uses a mirror and prism system 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.
A camera is an optical instrument used to capture and store images and videos, either digitally via an electronic image sensor, or chemically via a light-sensitive material such as photographic film. As a pivotal technology in the fields of photography and videography, cameras have played a significant role in the progression of visual arts, media, entertainment, surveillance, and scientific research. The invention of the camera dates back to the 19th century and has since evolved with advancements in technology, leading to a vast array of types and models in the 21st century.
A digital camera is a camera that captures photographs in digital memory. Most cameras produced today are digital, largely replacing those that capture images on photographic film. Digital cameras are now widely incorporated into mobile devices like smartphones with the same or more capabilities and features of dedicated cameras. High-end, high-definition dedicated cameras are still commonly used by professionals and those who desire to take higher-quality photographs.
A twin-lens reflex camera (TLR) is a type of camera with two objective lenses of the same focal length. One of the lenses is the photographic objective or "taking lens", while the other is used for the viewfinder system, which is usually viewed from above at waist level.
Victor Hasselblad AB is a Swedish manufacturer of medium format cameras, photographic equipment and image scanners based in Gothenburg, Sweden. The company originally became known for its classic analog medium-format cameras that used a waist-level viewfinder. Perhaps the most famous use of the Hasselblad camera was during the Apollo program missions when the first humans landed on the Moon. Almost all of the still photographs taken during these missions used modified Hasselblad cameras. In 2016, Hasselblad introduced the world's first digital compact mirrorless medium-format camera, the X1D-50c, changing the portability of medium-format photography. Hasselblad produces about 10,000 cameras a year from a small three-storey building.
A press camera is a medium or large format view camera that was predominantly used by press photographers in the early to mid-20th century. It was largely replaced for press photography by 35mm film cameras in the 1960s, and subsequently, by digital cameras. The quintessential press camera was the Speed Graphic. Press cameras are still used as portable and rugged view cameras.
Medium format has traditionally referred to a film format in photography and the related cameras and equipment that use film. Nowadays, the term applies to film and digital cameras that record images on media larger than the 24 mm × 36 mm used in 35 mm photography, but smaller than 4 in × 5 in.
Large format refers to any imaging format of 9 cm × 12 cm or larger. Large format is larger than "medium format", the 6 cm × 6 cm or 6 cm × 9 cm size of Hasselblad, Mamiya, Rollei, Kowa, and Pentax cameras, and much larger than the 24 mm × 36 mm frame of 35 mm format.
Mamiya Digital Imaging Co., Ltd. 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.
A digital camera back is a device that attaches to the back of a camera in place of the traditional negative film holder and contains an electronic image sensor. This allows cameras that were designed to use film take digital photographs. These camera backs are generally expensive by consumer standards and are primarily built to be attached on medium- and large-format cameras used by professional photographers.
Digital Negative (DNG) is an open, lossless raw image format developed by Adobe and used for digital photography. It was launched on September 27, 2004. The launch was accompanied by the first version of the DNG specification, plus various products, including a free-of-charge DNG converter utility. All Adobe photo manipulation software released since the launch supports DNG.
A digital single-lens reflex camera is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a solid-state image sensor and digitally records the images from the sensor.
Bronica also Zenza Bronica was a Japanese manufacturer of classic medium-format roll film cameras and photographic equipment based in Tokyo, Japan. Their single-lens reflex (SLR) system-cameras competed with Pentax, Hasselblad, Mamiya and others in the medium-format camera market.
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 so named because they are not yet processed, and contain large amounts of potentially redundant data. Normally, the image is processed by a raw converter, in a wide-gamut internal color space where precise adjustments can be made before 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.
Phase One is a Danish company specializing in high-end digital photography equipment and software. It manufactures open platform based medium format camera systems and solutions. Its RAW processing software, Capture One, supports many DSLRs besides their backs.
The merits of digital versus film photography were considered by photographers and filmmakers in the early 21st century after consumer digital cameras became widely available. Digital photography and digital cinematography have both advantages and disadvantages relative to still film and motion picture film photography. In the 21st century, photography came to be predominantly digital, but traditional photochemical methods continue to serve many users and applications.
The Nikon D7000 is a 16.2-megapixel digital single-lens reflex camera (DSLR) model announced by Nikon on September 15, 2010. It replaced the D90 as the top end consumer camera, by using much of the technology and controls from the earlier D5000, in a larger more robust body similar to the flagship D300 series. In some ways it was superior to the D300S, though for several years the two cameras were both available with the D300 positioned as the flagship in Nikon marketing materials.
The Fuji GX680 is a series of single lens reflex system cameras for medium format film produced by Fujifilm with interchangeable camera lenses and interchangeable film holders for the unusual film format 6×8 cm on 120 and 220 roll film. The distinguishing feature of the Fuji GX680 is the articulating front standard, which runs on a rail connecting lens and camera body by a bellows; the interchangeable lens is permanently mounted to a lens board.
The Mamiya 645 camera systems are a series of medium format film and digital cameras and lenses manufactured by Mamiya and its successors. They are called "645" because they use the nominal 6 cm x 4.5 cm film size from 120 roll film. They came in three major generations: first-generation manual-focus film cameras, second-generation manual-focus film cameras, and autofocus film/digital cameras.
The Mamiya RB67 is a professional medium format single-lens reflex system camera manufactured by Mamiya. There are three successive models: the RB67 Professional, RB67 Pro-S and RB67 Pro-SD. It is primarily designed for studio use, but can also be used in the field.
