Color Level

The Color Levle dialog box shows the distribution of brightness levels of the image and the level values shown in the Input Level and the Output Level entry boxes. To adjust the level, first choose the color channel. There are four radio boxes for the selection of channels. If you select the Master, the level of all three color channels (red, green and blue) will be adjusted simultaneously. If you select one of the Red, Green, or Blue boxes, then only the selected color channel will be adjusted. Next, you can adjust the level by dragging the triangular handles under the diagrams. The Black handle (the left one) is for the adjustment of the lower limit of input/output level, the gray handle (the middle one) is for the gamma, and the white handle (the right one) is for the upper limit. Dragging the three triangular handles under the input level diagram you can adjust the color level, and dragging the two handles under the output level diagram can lower the contrast of the image. In addition, you can adjust the values by directly entering the desired values in the entry boxes. You can also press the Auto button to let MiraScan automatically adjust the color level according to the color of the whole image. When you get the desired effect, press the OK button to confirm your settings. Otherwise, you can press the Reset button to reset them, or you can press the Cancel button to cancel your settings.
