Create Custom Tone Response Curve
Help Index
Advanced Feature
Creating an arbitrary tone response curve is an advanced feature not chosen by most
users. It is used to match unusual output devices such as film recorders or in other
special situations.
The Purpose of This Step
This screen allows you to create a custom non-Gamma curve as the desired tone
response of the monitor.
The Long Answer
Tone response is a description of how the monitor's output luminance reflects the
input signal. If you want to create a custom Tone Response Curve, click the Custom
button to create a new curve to your specifications.
In the Custom Curves Window you can define the shapes of the Composite, Red,
Green, and Blue curves by moving any of the seven adjustable control points up or
down with the up/down arrowheads below each control point. The input and updated
output value for the active point will be displayed below in the Input and Output fields.
Checking the "Preview" checkbox will cause the curve adjustments to effect your
display as you make them, allowing a real-time preview of the curves you are
creating. Custom Curve Sets can be saved by choosing the "Save" button and
providing a name. Saved sets can be opened by choosing the "Load" button and
selecting them by name.
