Color Page

The Color page lets you modify the brightness, and contrast of the colors in an image during a scan. Changes to these settings affect both the final scan and preview image.

The Brightness sliders let you independently adjust the brightness of red, green and blue tones in an image. The Contrast sliders let you adjust the balance of shadows and highlights for each color component in the image.

Default restores the sliders to their default values of 128, and Restore resets all the slider bars to their last stored positions. The positions of the slider bars are stored each time you exit from Corel TWAIN.

Gray Page

The Gray page lets you modify the scanning parameters for grayscale images. Changes to these settings affect both the final scan and preview image.

The Gray Balance slider lets you adjust the balance of grayscale shades in the image. This control works much like the Gray Contrast control, except that where contrast adjusts the values of shadows and highlights, Gray Balance adjusts all the tones in the image. Use this control to adjust grayscale tones globally. For finer control of specific tones use the Shift, Bright and Contrast controls.

The Gray Shift slider lets you adjust the brightness of midtones. The Gray Shift slider controls shift in the gamma curve used to adjust midtone values. Higher values brighten midtones and lower values darken them.

The Gray Bright slider lets you adjust the brightness of the entire image and the Gray Contrast slider lets you adjust the balance between highlights and shadows in the image.

Default restores the sliders to their default values of 128 and Restore to resets all of the slider bars to their last stored positions. The positions of the slider bars are stored each time you exit from Corel TWAIN.

The Film page lets you modify the color balance, and brightness of colors in images scanned from film. Changes to these settings affect both the final scan and preview image.

The Balance sliders let you independently adjust the balance of red, green and blue shades in an image. The Shift sliders let you adjust the brightness of color midtones.

Default restores the sliders to their default values of 128, and Restore resets all the slider bars to their last stored positions. The positions of the slider bars are stored each time you exit from Corel TWAIN.

Tool Page

The Tool offers you advanced options for scanning images from film or slides. Using these options you can control the time the film is exposed to the scanning head, or select a film type. The Averaging option averages adjacent pixel data creating a smoothing effect. Use this option to remove unwanted noise from your images.

The Gamma option controls the type of gamma correction applied to the scanned image. When the option is enabled, the scanner uses Analog Gamma correction. This type of gamma correction extends high density areas of film. The density of film greatly effects the quality of the scanned image. Film that is too dense may result in extra data in the image and film that is too thin may result in loss of image data.

Automatically sets the exposure time. The scanner examines the film and sets the best exposure time.


Averages adjacent pixel data creating a smoothing effect. This option greatly increases scanning time, so only enable it when necessary.


Controls the type of gamma correction applied to the image. When enabled, the scanner uses Analog gamma correction. When disabled, the scanner uses Linear Gamma correction.

Analog Gamma

Analog gamma correction extends high density areas of film. The density of film greatly effects the quality of the scanned image. Film that is too dense may result in extra data in the image and film that is too thin may result in loss of image data. By extending high density areas, you’re ensuring that details in those areas are properly captured by the scanner.

Linear Gamma

Linear Gamma correction does not detect film density. RGB gamma correction is applied to the entire area of the film equally.


This option box lets you select the type of film you’re scanning.


Resets options the their last stored values. Values are stored each time you exit Corel TWAIN.


Defines the amount of time the film is exposed to the scanning head.
