If the slider is moved to the extremes, the other objects will lose their properties and become
non-transparent; this is why the function should be applied sparingly so that small differences are
still discernible in the distribution of the black background.
The successive step is to obtain a uniform distribution of white on objects which will remain fully
non-transparent. This uneven distribution may arise from the fact that the colours of the object may
have colour components close to the keying colour. In this case an adjustment can be made using
the function known as White level.

In many cases, the option White level will be used in conjunction with the option Black level in
order to obtain possibly most effective settings of the black background, with no losses on white
objects and vice versa.
Picture from a camera will always contain some noise; the DVK 300 enables automatic correction
of interference by means of the Denoise option, which has two settings: standard and high.
