Colour Decision List (CDL)
CDL Parameter in the Selector
CDL Menu
The
CDL menu allows you to:
- Change the three basic transfer functions
(slope, offset, and power).
- Select whether you would like the transfer
functions to be applied before, or after, an Input LUT is applied.
- Enable or disable the transfer functions
you have set.
To access the CDL menu:
- In the main menu, click Image.
- Click CDL.
The CDL menu is displayed.
NoteThe CDL panel is
not accessible from the ACS or the CP-100.
Slope
When
you change the slope transfer function, it allows you to change
the lift and gain of the image without shifting the black level
that is established by the offset. The following is a graph displaying
how the slope value affects your image.
The following are the
values to set the slope:
- Default value is 1.00 (i.e., no value).
- Minimum value is 0.00.
- Maximum value is 5.00.
Offset
The
offset transfer function either raises or lowers the overall brightness
of the component, while keeping the slope constant.
The following are the
values to set the offset:
- Default value is 0.00 (i.e., no value).
- Minimum value is -5.00.
- Maximum value is 5.00.
Power
The
power transfer function changes the intermediate shape and is the
only non-linear function.
The following are the
values to set the power:
- Default value is 1.00 (i.e., no value).
- Minimum value is 0.00.
- Maximum value is 5.00.
Pre/Post Input LUT
You can decide to apply
the CDL data either before (Pre) or after (Post) applying an Input
LUT.
NoteApplying CDL data
after applying an Input LUT will work only if the Input LUT is enabled
within the Input LUT module.
CDL On/Off
The CDL On/Off toggle
allows you to either enable or disable CDL data. Since the Bypass
All function does not bypass both the Input LUT and CDL, you would
use the CDL On/Off button to 'mute' the effect of the CDL.
