Sheet Film
Sheet film is large format and Medium format (film), 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 Photographic_plate, 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 ...

Large Format
Large format photography 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 film, 120- and 220-roll film), and much larger than the frame of 135 film, 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 times 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 , which was the size used by cameras like the Graflex Speed Graphi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Contact Print
A contact print is a photographic image produced from Photographic film, film; sometimes from a film negative (photography), 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 film developing, 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 ease ...

Film Format
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 Anamorphosis is a distorted projection that requires the viewer to occupy a specific vantage point, use special devices, or both to view a recognizable image. It is used in painting, photography, sculpture and installation, toys, and film speci ... (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.

View Camera
A view camera is a large format, large-format camera in which the large format lens, lens forms an erect image, inverted image on a ground glass, ground-glass screen directly at the film plane. The image is viewed, composed, and focused, then the glass screen is replaced with the photographic film, film to exposure (photography), expose exactly the same image seen on the screen. This type of camera was developed during the era of the daguerreotypeStroebel, L. D. (1986). ''View Camera Technique'', 5th ed., p. 212. Boston: Focal Press. (1840s–1850s) and is still in use, some using drive mechanisms for movement (rather than loosen-move-tighten), more scale markings, and/or more spirit levels. It comprises a flexible bellows (photography), bellows that forms a light-tight seal between two adjustable ''standards'', one of which holds a Photographic lens, lens, and the other a ground glass or a photographic film holder or a digital back.Stroebel (1986). p. 2.
