Color Wheel

A representation of colors and their complements.

Complementary Colors

Red, green, and blue can be thought of as complementary colors to cyan, magenta, and yellow. These colors cancel each other out when combined in equal amounts. Similarly, adding a small amount of one color reduces its complement by that amount.

Contrast

Contrast refers to the difference between the lightest light and the darkest dark in the image. A low contrast value indicates that the difference between dark shades and light shades is not very great. A high value indicates a great difference between dark and light shades. While brightness refers to the intensity of tones in an image, contrast refers to the range and number of tones in an image.

Crop

The action of selecting part of an image. The Crop tool on the main ScanGear CS-S window lets you select part of a preview image and re-preview or scan only that selected part.

Curve Chart

The graph displayed in the Tone tab settings for the Auto Tone, Contrast/ Brightness, Gamma, Histogram, and Special Tone Curves features. This graph describes the relationship between the color characteristics of the previewed image and the available feature settings.

Curve File

A file containing Special Tone Curve settings. (Tone tab - Special Tone Curves)

Custom Curves

A user-defined Special Tone Curve that may be saved in a file. (Tone tab - Special Tone Curves)

Custom Resolutions

The Custom Resolutions dialog box lets you create a scan resolution not found in the preset list, but supported by the input device.

Default

The preset factory settings on hardware or software.
