5.2.1 Settings in the Lighting Region

You can correct the exposure with Nero PhotoSnap. For this purpose there is a histogram

and gradation correction curve available in the Color/Exposure area.

The following tabs are available:

Histogram

Correction

This defines the brightness range of the histogram using two lines. On the

left are the light pixels, on the right the dark pixels. The histogram is recor-

ded in the background.

Gravitation

curves

Defines the distribution of the brightness values using a curve. On the X

axis are the hue values of the original from light to dark, on the Y axis the

tone values after the correction from light to dark. A straight curve with a

45° angle means that the original values remain unchanged. The

histogram is recorded in the background.

The histogram graphically shows the brightness distribution of the picture pix-

els. On the X axis are the hue values from 0 (light) to 255 (dark), on the Y axis

the number of pixels.
