Betterlight: also the scanback, also the company that makes the scanback.

camerastand: the whole rig that holds up the camera.

CCD: the digital eye that sits inside the scanback. this device is similar to a flatbeds scanhead, however much smaller, more powerful, and more expensive.  :)

color space: is a set of reproducible colors defined by a color format

DPI: stands for "dots per inch" also referred to as resolution.

focus card: creditcard size plastic card with horizontal and vertical lines, used to help focus the camera.

gamut: is the current range of colors found and available within a particular image.

greyscale: is a range of progressing tones from black to white.

greyscale card: long paper card with several pantone color chips attached forming a gradient of tones from white to black. used to help color correct scans.

histogram: is a graphical representation (in most cases a bar graph) of the amounts of certain tones within a gamut. this allows you to quickly see what the composition of tones are within your image.

marque selection: is the rectangle of flashing black and white dashes that indicate an area to be effected.

pantone colors: are a certain set of standardized colors that can be accurately represented and calibrated in both screen and print media.

pips: small square boxes on the corners and sides of a selection or transform box that you can click and drag to change the format of the selection, also the name for a movable handle on any editable vector.

scanback: the piece of hardware where the ccd is housed, that sits in the camera. This is the thing that does the scanning.

scan head: is the movable part of the scanback that holds the CCD and moves across the materials to be imaged.

scan table: the part of the camerastand where materials to be scanned are placed for scanning.

tone: refers to any certain value on a scale from black to white.

tone curve: is a graphical representation which shows the amount of weight, based on steepness of the curve, that the tones within a gamut will hold. this allows you to smoothly and visually edit an entire gamut of tone

Viewfinder: the program that runs the betterlight scanback. We are running V. 4.1.2
