Professional Mode

If the two above-described modes don’t suit you, and you feel yourself experienced in the scanning field, here’s your mode in which you set up all digitization parameters manually. For easier navigation, the parameters window is divided into three thematic sections: Original, Destination and Adjustments.

The Original section is for selecting the type of the original

The Destination section is for choosing the parameters
of digitization quality and dimensions

The Adjustment section is for activating
additional image correction tools

There are four icons in the section that contains image correction settings. The first icon looks like a sphere – it activates the Auto Exposure function. The result of this function is immediately displayed in the preview window.

Histogram Adjustment

The second icon displays a histogram. You click it to open the Histogram Adjustment window where, unlike with the Auto Exposure function, the user can manually set up the level of each color channel. This function is analogous to the Levels conversion in Photoshop.

Tone Correction

The third icon opens up the tone correction window. This function is analogous to the Curve tool in Photoshop with only one exception: here we have a number of presets of varying brightness and contrast.
