Stat Camera
A stat camera is a large-format vertical or horizontal stationary camera used to shoot film for camera-ready artwork, and sometimes called a copy camera. This is a large bellows-type camera which consists of the copy-board, bellows and lens, and filmboard. The vertical type can take up relatively little space, while the horizontal fills two rooms; bellows, lens, and copyboard on one side of the wall; filmboard and darkroom on the other. The type of film used is black and white "orthochromatic"; i.e., it is more sensitive to some colors than others. Guidelines, or "keylines" are created in light blue which read as white; while anything red or close to a red hue appears as black. The stat camera would be used to shoot color separations (using hue filters for each of the four process colors) and to produce halftone film for printing using a special reticulated gel mask. Screen printers will use the films, or 'positives', to expose the silk screen. This process is invaluable to di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camera
A camera is an Optics, optical instrument that can capture an image. Most cameras can capture 2D images, with some more advanced models being able to capture 3D images. At a basic level, most cameras consist of sealed boxes (the camera body), with a small hole (the aperture) that allows light to pass through in order to capture an image on a light-sensitive surface (usually a Image sensor, digital sensor or photographic film). Cameras have various mechanisms to control how the light falls onto the light-sensitive surface. Lenses focus the light entering the camera, and the aperture can be narrowed or widened. A Shutter (photography), shutter mechanism determines the amount of time the photosensitive surface is exposed to the light. The still image camera is the main instrument in the art of photography. Captured images may be reproduced later as part of the process of photography, digital imaging, or photographic printing. Similar artistic fields in the moving-image camera dom ...

Camera-ready
Camera-ready is a common term used in the commercial printing industry meaning that a document is, from a technical standpoint, ready to "go to press", or be printed. History The term camera-ready was first used in the photo offset printing process, where the final layout of a document was attached to a "mechanical" or "paste up". Then, a stat camera was used to photograph the mechanical, and the final offset printing plates were created from the camera's negative. In this system, a final paste-up that needed no further changes or additions was ready to be photographed by the process camera and subsequently printed. This final document was ''camera-ready''. This artwork may have looked messy to the naked eye or to a modern consumer digital camera - covered in various pieces of paper attached with adhesive or wax and composited with white out, gouache, tape and blue pencil (non-reproducible) and red masking film, black or clay-based paint (reproducible as black) - but appear ...

Color Separation
Color printing or colour printing is the reproduction of an image or text in color (as opposed to simpler black and white or monochrome printing). Any natural scene or color photograph can be optically and physiologically dissected into three primary colors, red, green and blue, roughly equal amounts of which give rise to the perception of white, and different proportions of which give rise to the visual sensations of all other colors. The additive combination of any two primary colors in roughly equal proportion gives rise to the perception of a secondary color. For example, red and green yields yellow, red and blue yields magenta (a purple hue), and green and blue yield cyan (a turquoise hue). Only yellow is counter-intuitive. Yellow, cyan and magenta are merely the "basic" secondary colors: unequal mixtures of the primaries give rise to perception of many other colors all of which may be co Modern techniques While there are many techniques for reproducing images in color, ...

Filter (photography)
In photography and cinematography, a filter is a camera accessory consisting of an optical filter that can be inserted into the optical path. The filter can be of a square or oblong shape and mounted in a holder accessory, or, more commonly, a glass or plastic disk in a metal or plastic ring frame, which can be screwed into the front of or clipped onto the camera lens. Filters modify the images recorded. Sometimes they are used to make only subtle changes to images; other times the image would simply not be possible without them. In monochrome photography, coloured filters affect the relative brightness of different colours; red lipstick may be rendered as anything from almost white to almost black with different filters. Others change the colour balance of images, so that photographs under incandescent lighting show colours as they are perceived, rather than with a reddish tinge. There are filters that distort the image in a desired way, diffusing an otherwise sharp image, addin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halftone
Halftone is the reprographic Reprography (a portmanteau of ''reproduction'' and ''photography'') is the reproduction of graphics through mechanical or electrical means, such as photography or xerography. Reprography is commonly used in catalogs and archives, as well as in th ... technique that simulates continuous-tone imagery through the use of dots, varying either in size or in spacing, thus generating a gradient-like effect.Campbell, Alastair. The Designer's Lexicon. ©2000 Chronicle, San Francisco. "Halftone" can also be used to refer specifically to the image that is produced by this process. Where continuous-tone imagery contains an infinite range of colors or greys, the halftone process reduces visual reproductions to an image that is printed with only one color of ink, in dots of differing size (pulse-width modulation) or spacing (frequency modulation) or both. This reproduction relies on a basic optical illusion: when the halftone dots are small, the human eye inter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-end
In economics, a luxury good (or upmarket good) is a good for which demand increases more than what is proportional as income rises, so that expenditures on the good become a greater proportion of overall spending. Luxury goods are in contrast to necessity goods, where demand increases proportionally less than income. ''Luxury goods'' is often used synonymously with ''superior goods''. Definition The word "luxury" originated from the Latin word ''luxuria'', which means exuberance, excess, or abundance. A luxury good can be identified by comparing the demand for the good at one point in time against the demand for the good at a different point in time, at a different income level. When personal income increases, demand for luxury goods increases even more than income does. Conversely, when personal income decreases, demand for luxury goods drops even more than income does. For example, if income rises 1%, and the demand for a product rises 2%, then the product is a luxury good. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
