Histogram

When the Image Tools dialogue window appears, an image histogram will be displayed in the

window. The image histogram is a graphical representation of the distribution of RGB and/or

luminance values in an image. Each of the values appear on the horizontal axis from dark to light,

(left to right), as shown in the Histogram graphics below. The vertical axis indicates the number of

pixels of that value at each point. At a point where there are many pixels of a value, the

corresponding line spikes; where there are no pixels, it lies at the bottom of the graph.

Move the appropriate slider, to apply the desired image processing adjustment to the images being

displayed in the active Preview or Playback Panel. The sliders can be used to adjust the following

image processing adjustments:

Brightness

This slide bar is used to adjust the brightness of monochrome or color images. The factory

default value is set to 0 (zero). Moving the slide bar to the left, in the negative direction from 0,

results in the images being displayed darker, while moving the slide bar to the right or in a

positive direction from 0 results in the images being displayed lighter.
