Microtek ArtixScan M1 Pro User Manual page 29

ScanWizard Pro lets you choose the color space in which you wish to edit and work
with color images.
• Select LCH mode if you wish to edit or correct images in terms of color percep-
tion according to the human eye, based on the properties of Lightness, Chroma,
and Hue. This is the default mode.
• Select Native mode if you wish to edit or correct the individual RGB / CMYK
channels of an image.
To switch between LCH and Native color modes, go to the Preferences | More
command in the Preview window. When the More Preferences dialog box comes up,
go to the Working Color Space option, and choose LCH or Native as the color mode
you wish.
