Film Holder
A film holder is a accessory that holds one or more pieces of photographic film, for insertion into a camera or optical scanning device such as a dedicated film scanner or a flatbed scanner with film scanning capabilities. The widest use of the term refers to a device that holds sheet film for use in large format cameras, but it can also refer to various interchangeable devices in medium format or even 135 film camera systems. Sheet film holders The most common instance of film holder is the sheet film holder. Also referred to as a ''dark slide'' or ''double dark slide'', they are flat devices, slightly larger than the films they hold, which commonly hold one sheet of film on each side. The plate holder, which is a very similar device, holds glass plates instead of sheet film. A dark slide, from which the device derives its alternate name, is simply a dark cover that slides into a recess in the holder to protect the film (or plate) from exposure to light. Many dark slides have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photographic
Photography is the art, application, and practice of creating durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purpose ...

Contact Printing
A contact print is a photographic image produced from film; sometimes from a film negative, and sometimes from a film positive or paper negative. In a darkroom an exposed and developed piece of film or photographic paper is placed emulsion side down, in contact with a piece of photographic paper, light is briefly shone through the negative or paper and then the paper is developed to reveal the final print. The defining characteristic of a contact print is that the resulting print is the same size as the original, rather than having been projected through an enlarger. Basic tools Contact printing is a simple and inexpensive process. Its simplicity avails itself to those who may want to try darkroom processing without buying an enlarger. One or more negatives are placed on a sheet of photographic paper which is briefly exposed to a light source. The light may come from a low wattage frosted bulb hanging above an easel which holds them together, or contained in an exposure ...

Sheet Film
Sheet film is large format and medium format photographic film supplied on individual sheets of acetate or polyester film base rather than rolls. Sheet film was initially supplied as an alternative to glass plates. The most popular size measures ; smaller and larger sizes including the gigantic have been made and many are still available today. Using sheet film To use sheet film, the photographer places a sheet of film, emulsion side out, into a film holder in the dark, and closes the dark slide over the loaded film. Next, the holder is inserted into a large-format camera, and the dark slide is removed from the holder. The exposure is made, the dark slide is replaced, and the film holder is removed from the camera. Notches Sheet films have notches cut into one short side. This makes it simple to determine which side is the emulsion, when the film is hidden from sight (in the darkroom, or inside a changing bag). When holding the sheet in "portrait" orientation (short si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medium Format
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 used in 35 mm photography (though not including 127 sizes), but smaller than (which is considered large format photography). In digital photography, medium format refers either to cameras adapted from medium-format film photography uses or to cameras making use of sensors larger than that of a 35 mm film frame. Some of the benefits of using medium-format digital cameras include higher resolution sensors, better low-light capabilities compared to a traditional 35mm DSLR, and a wider dynamic range. Characteristics Medium-format cameras made since the 1950s are generally less automated than smaller cameras made at the same time. For example, autofocus became available in consumer 35 mm cameras in 1977, but did not reach medium format until ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Large Format
Large format refers to any imaging format of or larger. Large format is larger than "medium format", the or size of Hasselblad, Mamiya, Rollei, Kowa, and Pentax cameras (using 120- and 220-roll film), and much larger than the frame of 35 mm format. The main advantage of a large format, film or digital, is a higher resolution at the same pixel pitch, or the same resolution with larger pixels or grains which allows each pixel to capture more light enabling exceptional low-light capture. A 4×5 inch image (12.903 mm²) has about 15 times the area, and thus 15× the total resolution, of a 35 mm frame (864 mm²). Large format cameras were some of the earliest photographic devices, and before enlargers were common, it was normal to just make 1:1 contact prints from a 4×5, 5×7, or 8×10-inch negative. Formats The most common large format is 4×5 inches (10.2x12.7 cm), which was the size used by cameras like the Graflex Speed Graphic and Crown Gr ...

Film Scanner
A film scanner is a device made for scanning photographic film directly into a computer without the use of any intermediate printmaking. It provides several benefits over using a flatbed scanner to scan in a print of any size: the photographer has direct control over cropping and aspect ratio from the original, unmolested image on film; and many film scanners have special software or hardware that removes scratches and film grain and improves color reproduction from film. Film scanners can accept either strips of 35 mm or 120 film, or individual slides. Low-end scanners typically only take 35mm film strips, while medium- and high-end film scanners often have interchangeable film loaders. This allows the one scanning platform to be used for different sizes and packaging. For example, some allow microscope slides to be loaded for scanning, while mechanised slide loaders allow many individual slides to be batch scanned unattended. Some software used to process images scanned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Film Formats
A film format is a technical definition of a set of standard characteristics regarding image capture on photographic film for still images or film stock for filmmaking. It can also apply to projected film, either slides or movies. The primary characteristic of a film format is its size and shape. In the case of motion picture film, the format sometimes includes audio parameters. Other characteristics usually include the film gauge, pulldown method, lens anamorphosis (or lack thereof), and film gate or projector aperture dimensions, all of which need to be defined for photography as well as projection, as they may differ. Motion picture film formats Digital camera formats Photographic film formats See also *Film base * Keykode *Large format *Medium format *Microform Microforms are scaled-down reproductions of documents, typically either films or paper, made for the purposes of transmission, storage, reading, and printing. Microform images are commonly reduced to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Press Camera
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. Details Press cameras were widely used from the 1900s through the early 1960s and commonly have the following features: * collapsible into strong, compact boxes * flexible bellows, attached to a flatbed track * easily interchangeable lenses, mounted on a solid support * ability to accept sheet film, film packs, and roll film, through the use of interchangeable film backs and holders * ground glass focusing screen * optical viewfinder * handheld operation * reduced number, reduced range or absence of movements, in contrast to field cameras or other view camera formats * optical rangefinder focusing in so ...

Instant Film
Instant film is a type of photographic film that was introduced by Polaroid Corporation to produce a visible image within minutes or seconds of the photograph's exposure. The film contains the chemicals needed for developing and fixing the photograph, and the camera exposes and initiates the developing process after a photo has been taken. In earlier Polaroid instant cameras the film is pulled through rollers, breaking open a pod containing a reagent that is spread between the exposed negative and receiving positive sheet. This film sandwich develops for some time after which the positive sheet is peeled away from the negative to reveal the developed photo. In 1972, Polaroid introduced ''integral film'', which incorporated timing and receiving layers to automatically develop and fix the photo without any intervention from the photographer. Instant film has been available in sizes from (similar to 135 film) up to size, with the most popular film sizes for consumer snapshots be ...

Komamura Corporation
is a Japanese company that most notably manufactured medium- and large-format cameras. The company's first camera, the PC-101, was offered in 1948 as a police inspection camera; this was soon developed into a press camera, the Horseman 102, which was the first Horseman Professional branded camera. History In 1933, Komamura Brothers was founded in Kyoto; the first camera produced was the PC-101, an inspection camera for the National Police Agency produced in 1948. This was developed into the Horseman 102, which was also designed for police inspection and offered in 1950. Komamura relocated in Tokyo in 1982. In 1992, Komamura signed the first of several licensing agreements to be the exclusive distributor for foreign photographic and video products in Japan, including Rodenstock and Schneider Kreuznach lenses, Gossen light meters, and Anton Bauer batteries.
