1. CRT Gamma

CRT is a gamma function to compensate the gamma of a picture monitor.

In order to judge a picture content (in terms of gradation) by looking at a moni-

tor, CRT has to be switched on.

When working with Data, the end product is not necessarily video or a TV pic-

ture but a picture recorded back on film or a picture which will be projected by

a video beamer. In this case, a Output LUT (lookup table) will be chosen that

replaces the CRT gamma by its own characteristic.

Depending on the selected Output LUT, CRT GAMMA will automatically be

switched on or off.

Note! CRT GAMMA in Data mode is only active with TVLEV and GRLEV.

When CRT Gamma is active, the green bar on the button is lit.

2. Control Range

This button switches the range of Black, RGB Black, Gamma, RGB Gamma,

WHITE and RGB White from Normal to Extended Range.

Pressing Unity leads to different values in Extended Range mode compared to

Normal mode.

In Extended Ranges mode, Master Gamma changes can affect the Blacks and

Whites in your picture, whereas in Normal mode only the gray tones are ad-

dressed.

Therefore adjust Gamma first, then do BLACK (Lift) and WHITE (Gain).

Changing from Normal to Extended Ranges within a programmed list requires

re-adjustment of Black, Gamma and White.

Dependent on the grading, Extended Ranges may increase noise.
