A view after a White level adjustment
In many cases, the option White Level will be used in conjunction with the option Black Level
in order to obtain the most possible effective settings of the black background, with no loss on
white objects and vice versa.

Tolerance Correction
As seen in the view after a White Level adjustment, an extension of the range by means of the
White Level function usually results in the restoration of a uniformly black surface to slight
grays. In this case, in order to adjust the grayness, two further functions from the Tolerance
correction section are needed. Click the tolerance correction button
to enter the
Tolerance Correction configuration screen.
The first function is Luminance and it improves the structure of the uniform colour of the
white mask.
