Software Guide (Scanning)

A histogram allows you to see the data concentration at each brightness level of an image. You can

specify the darkest and brightest levels within an image, cut the levels and expand the middle of the tonal

range of the image.

The gamma is active if [Color (photo)], [Color (Documents)] or [Greyscale] is selected in [Color Mode].

You can set up the histogram without having to display a preview and the settings will be active when you

scan.

In ScanGear MP Advanced Mode, follow the steps below.

1 Click [Reset].

2 On the [Color] tab, click (Histogram).

3 For a color image, in [Channel], select a color.

4 To change the black-point, mid-point or white-point, do one of the following.

¡¡

Click the [Black-point] and select the darkest area in the preview image.

You can also enter a value (0 to 245).

Click the [Mid-point] and select the area in the middle of the tonal range.

You can also enter a value (5 to 250).

Click the [White-point] and select the lightest area.

You can also enter a value (10 to 255).
