Parametric Controls for HDR Transforms and Color Correction

FS-HDR provides 21 parametric controls for Colorfront Engine FS-HDR HDR transforms and color correction. Each parametric control is accessible via FS-HDR’s front panel, the web GUI on any browser, or REST interface, and settings can be stored to a preset for recall later or copied to other FS-HDR units.

Twenty one individual parametric controls enable the following:
- Adjusting R,G,B, and Master color controls for Lift, Gamma, and Gain
- Adjusting Saturation
- Guiding the algorithm’s color volume expansion from SDR to HDR
- Adjusting for the Ambient Light in the mastering or viewing environment
- Managing how SDR highlights and speculars are expanded into HDR
- Controlling the overall look of camera log inputs between cinematic and television
- Support for ITU BT.2408-0, Operational Practices in HDR Television Production.

SDR Preview Mode

The Colorfront Engine SDR Preview Mode allows a user to quickly see what an HDR output will look like if it were converted to SDR by an FS-HDR. This is extremely useful in functions like camera shading, where the operator is making adjustments to an HDR camera while viewing the image on an HDR display. A key question is "what will this picture look like when down converted to SDR?" The FS-HDR's unique SDR Preview mode provides a fast way to answer this question without requiring an HDR to SDR equipment chain or reconfiguring the existing HDR monitor.

When SDR Preview is enabled, the Colorfront Engine maps the video into the currently selected HDR space (PQ or HLG), but with values that will exactly represent the SDR image. This eliminates the time normally required to change the output format to SDR and the wait for the display to reconfigure. By simply controlling the on/off state of SDR Preview (from the front panel, Web GUI, or GPI), the operator can make quick, glitch free A/B comparisons of the HDR and SDR images.
