Light > Auto Levels

The Auto Levels tool enables Capture NX 2 to analyze your image in order to determine the correct adjustments to spread the available color information across the entire

range of tonal possibilities. While similar to the auto contrast button within the Levels & Curves step, the Auto Levels

tool provides you with additional controls.

The Auto Levels tool provides you with the following controls:

Auto Levels Method

Click on the auto levels method pull-down menu to select between one of the two possible methods:

Auto

The Auto method results in a redistribution of the

individual color channels, similar to stretching each color channel within the Levels & Curves tool to the entire

range of the histogram.

Advanced

The Advanced method begins with the same results as the Auto method, but provides you with access to the Correct Contrast and Correct Color Cast sliders.

Correct Contrast

The Correct Contrast slider is provided by selecting the Advanced method in the auto levels method pull-down menu. Use this slider to either increase or decrease the amount of contrast that is applied to your image. A value of 50 is equivalent to the contrast effect of the Auto method.
