Unsharp Mask

Digital ICE cubed

Unsharp mask increases the sharpness of the image by making edges more distinct, either over the entire image or in areas where spe- cific colors are prominent.

Three tools are available:

Digital ICE: reduces the effects of dust and scratches

Digtial ROC: restores colors lost through fad- ing

Digital GEM: reduces the effect of film grain

Analog Gain

Scanner Extras

Using analog gain, you can adjust colors by di- rectly altering the exposure value for each of the colored elements in the scanner’s light source.

These tools offer control over features specific to your scanner.
