Histogram
The histogram is a graphic representation of how all the pixels in an image
are distributed across brightness and darkness levels. The darkest pixels
are at the left; the lightest pixels are at the right.
A histogram skewed heavily to the left indicates that the image has many
more dark pixels than light. Conversely, a histogram skewed heavily to the
right will indicate a light image as it has more light pixels than dark. The
height of the histogram indicates the number of pixels at that point in the
histogram.
Sliders
The sliders are used to adjust the Black and White points of the image.
The values of the black and white points are reflected in the edit boxes.
Pickers
The Pickers can be used instead of the sliders to set the Black and White
points, based on color values in the preview image. The Picker on the left
sets the Black point; the Picker on the right sets the White point.
● To set the White point: Click the Picker on the right, then click on the
preview image to define the reference point.
● To set the Black point: Click the Picker on the left, then click on the
preview image to define the reference point.
