• Luma Keying is used to key from a parcular luminous intensity. It produces a hard edged key based on
intensity, which is most suitable for tling eects. You can choose to key things that are extremely dark or
extremely bright and keep everything in between, or invert to key only things that are of a medium intensity.
• The black and white levels dene where to begin the keying. In the range 0 to 255, 0 represents no luminance,
or black and 255 represents full luminance, or white.
- Level Black: As the Black Level is changed from 0 to 255, things that are black are rst keyed out, followed
by dark grey, then light grey, and so forth, unl the enre picture is keyed out at 255.

Chroma Keying is used to key from a parcular color. It produces a key which is most suitable for moving

Using a crosshair, you can select a parcular hue based on what is on screen. Once you have adjusted the
crosshairs to a desired posion, press set/enter to capture the color value at that instant. You can then adjust
the other parameters such as Tolerance to further rene your key.
