Adjusting Tone Curve You can adjust the brightness of an image by selecting the type of graph (tone curve) showing the balance of tone input and output, via tab. (Tone Curve Settings) in ScanGear (scanner driver)'s Advanced Mode Note • Click Defaults to reset all adjustments in the current window. Channel Each dot of an image is a mixture of Red, Green, and Blue in various proportions (gradation). These colors can be adjusted individually as a "channel." Master Adjust the Red, Green, and Blue combined. Red Adjust the Red channel. Green Adjust the Green channel. Blue Adjust the Blue channel. Note • Only Grayscale will be displayed in Channel when Color Mode is Grayscale. Reading Tone Curves With ScanGear, scanning images via a scanner is the input, and displaying to a monitor is the output. "Tone Curve" shows the balance of tone input and output for each Channel. 736
