Tone Mapping Method: Lets you enable tone mapping, to accommodate workflows
where you need to transform one color space into another with a dramatically larger or
smaller dynamic range by automating an expansion or contraction of image contrast in
such a way as to give a pleasing result with no clipping. There are three options, None,
Simple, and Luminance Mapping.
Choosing “Simple“ uses a simple curve to perform this transformation, compressing
or expanding the highlights and/or shadows of the timeline dynamic range to
better fit the output dynamic range. Note that the “Simple” option maps between
approximately 5500 nits and 100 nits, so if you’re mapping from an HDR source with
more than 5500 nits to an SDR destination there may still be some clipping of the
highlights above 5500 nits.
Choosing “Luminance Mapping” lets you use a customized curve operation to
remap the gamma of the image and enables the Max. Input Luminance, Max. Output
Luminance, and Avg. Input Luminance sliders.
The Max. Input Luminance slider lets you set the reference maximum Luminance
value (in nits) that you want to remap to the value set by the Max. Output Luminance
slider, which governs the maximum luminance level of the Output color space (in
nits). Using these two sliders together, you can set which value from the Input
Gamma is mapped to which value of the Output Gamma.
The Avg. Input Luminance slider is designed to compensate for large differences in
the viewer’s state of visual adaptation when viewing a bright image on an HDR
display versus seeing that same image on an SDR display. For most “average”
images this setting works best set between 0–10. However, when you’re converting
very bright images (for example, a snow scene at noon), then using a higher value
will yield more image detail within the highlights.
Gamut Mapping Method: Accommodates workflows where you need to transform
one color space into another with a dramatically larger or smaller gamut by helping to
automate an expansion or contraction of image saturation in such a way as to give a
pleasing and naturalistic result with no clipping. Choosing Saturation Mapping lets you
remap the saturation values of the image. It enables the Saturation Knee and Saturation
Max. controls.
The Saturation Knee slider sets the image level at which saturation mapping begins.
Below this level, no remapping is applied. All saturation values from this level on
up are remapped according to the Saturation Max. slider. A value of 1.0 is maximum
saturation in the currently selected output color space.
The Saturation Max slider sets the new maximum level to which you want to either
raise or lower all saturation values that are above the Saturation Knee setting.
A value of 1.0 is maximum saturation in the currently selected output color space.
Invert Color
A Color category plug-in that lets you invert any color channel, including the alpha channel. This
little plug-in has 101 uses in advanced workflows, especially when you need to invert Alpha or
Key channels to do something specific. This is not a “film negative” plug-in; this is a simple
inversion.
