S-RAM

Definition: (Static RAM) The most expensive type of RAM found in on-board memory units, some printers, and in PCMCIA Type I Cards. D-RAM, Dynamic Ram. Most often seen as the expandable RAM used by the computer for memory.

SABANIER EFFECT

Definition: A partial reversal of tones that occurs when film or paper is reexposed to light during development. Commonly called solarization.

SABATTIER EFFECT

Definition: part positive part negative effect formed when an emulsion is briefly re-exposed to white light during development, and then allowed to continue development. Also known as pseudo-solarization.

SAFELIGHT

Definition: darkroom light of a color and intensity that will not affect light sensitized photographic materials.

Definition: A special darkroom lamp whose light is of colour and intensity that will not affect light-sensitive photographic material. Not all such material can be handled under a safelight, and some required a type designed specifically for them.

Definition: An enclosed darkroom lamp fitted with a filter to screen out light rays to which film and paper are sensitive.

SAFETY FILM

Definition: A photographic film whose base is fire-resistant or slow burning. At the present time, the terms "safety film" are synonymous.

Definition: term used to describe a film with a base that is not readily inflammable.

SAFETY INTERLOCK

Definition: A feature on all Kodak Advantix cameras that prevents the film door from opening mid-roll and exposing film to light.

SAL-AMMONIAC

Definition: ammonium chloride. used in some high speed developers.

SAMPLE

Definition: In imaging, to gather the value of a colour. to select an image colour to be used in a drawing or painting tool.

SANDWICHING

Definition: Combining two or more negatives or slides to produce a composite image either on one sheet of printing paper or on a slide-projecting screen.

SATURATED COLOR

Definition: pure color hue, undiluted by other colors, white or gray, i. e. the primary colors, red, yellow and blue are saturated colors.

SATURATION

Definition: The vividness or purity of a colour; the less gray a colour contains, the more saturated it is.

Definition: How rich the colors are in a photo.

Definition: An attribute of perceived color, or the percentage of hue in a color. Saturated colors are called vivid, strong, or deep. Desaturated colors are called dull, weak, or washed out.

SATURATION LEVELS

Definition: Light intensity that exceeds the maximum level designed for a CCD.

SCALE

Definition: linear relation between the size of the subject and the size of its image.

Definition: To change the proportion of an image by increasing or decreasing its size.

SCAN

Definition: The process of translating a picture from artwork or transparency into digital information. Screen Angles. In half-tone printing, these are the angles at which halftone screens are placed to avoid moire patterns on the final image. The most commonly used angles are Definition[ Black = 45 degrees; Magenta = 75 degrees; Yellow = 90 degrees; Cyan = 105 degrees.

SCAN SIZE

Definition: The length and width dimensions of the part of a document that can be digitized.

SCAN TIME:

Definition: The total time to convert text or graphical information into electronic raster form.

SCANNED IMAGE

Definition: The computer picture that results when a photograph, slide, paper imager, or other two or three dimensional images are converted into a digital image.

SCANNER

Definition: A device that captures an image for your computer and converts it to a digital form that your computer can display, edit store and output. A scanner can be used for a wide variety of application, such as incorporating artwork or photos into documents, scanning printed text into your word processor to eliminate retyping, scanning faxed document into a database for storage, and adding images to multimedia productions.

SCANNER THRESHOLD

Definition: Setting that determines whether a pixel is white or black.

SCANNING BACK

Definition: High quality digital camera back for medium or large format cameras which scans in three passes (RGB) one pass for each colour, therefore best used with still life subjects.
