Adjusting Foreground Flare Controls - Blackmagic Design Ultimatte 12 Manual De Operaciones

To generate noise:
1 Click on the 'noise cursor' button in the functions section to enable the cursor on the
foreground source.
2 Using the cursor position controls, place the cursor on an area of the foreground that
displays the most prominent noise.
3 Click on the 'noise select' button.
4 Click on the 'noise gen' button to enable noise generation.
5 Increase or decrease the amount of noise generation using the 'noise gen level' control.
Matte Reset
The matte reset button restores all matte controls, including matte density, black gloss, color
density, and shadow settings to their default settings. These default settings could be factory
set or user set values. For more information on customizing your Ultimatte, refer to the 'saving
and managing presets' section.
NOTE Matte reset does not sample the backing for new reference color values. The
current values are used to recalculate spill suppression with any adjusted background
settings.
Matte Button
Click this button to disable or enable the matte generation and flare settings. The default
setting of this button is 'enabled'.
Cursor Position Last
When this button is enabled, the cursor will return to the horizontal and vertical positions where
it was last used. This mode is helpful when studio cameras are mounted on robotics systems
and could be programmed to go to the same starting position, thus allowing the same exact
sampling locations to be used again. When you save a preset file, cursor location is also saved.
When disabled, the location of the cursor will always return to a default horizontal and vertical
position toward the top left hand corner of the image, regardless of the previously used
sampling location.
Auto Screen Sample
Auto screen sample is the default method of scanning, analyzing, and determining reference
backing color levels. Using this method, the matte signal is analyzed to detect the most
predominant highest level, which will correspond to the brightest and purest area of the
backing. Auto screen sample will also be performed during all of the functions listed below:
Main unit power up, system reset, backing color select, and auto key.

Adjusting Foreground Flare Controls

Your Ultimatte automatically analyzes the backing color reflecting onto foreground objects and
removes the effect of the bounce color in the final composite. This is called spill suppression.
The process of spill suppression can affect certain colors in the foreground. The colors affected
will vary depending on the backing color you are using. If you need to make color adjustments
to restore the original color of foreground elements, the results of spill suppression can be
adjusted using the flare controls.
