Scene sub-state – A dropdown list of all saved scene color corrections sub-states.

Create () – Creates a new scene color corrections sub-state.

Update () – Updates a scene color corrections sub-state.

Delete () – Deletes a scene color corrections sub-state. Double-click to delete.

Exposure corrections – Turns on/off exposure corrections.

Exposure bias – Adjusts the Exposure bias value.

Highlight burn – Applies exposure corrections to highlights in the image. This option is hidden when Filmic tonemap is on.

Contrast – Positive values push the colors away from the medium gray value to increase image contrast. Negative values push the colors closer to medium grey.

Filmic tonemap – Applies a parametric mapping curve and gamma correction. 

Type – Specifies the type of curves used for the tone mapping. You can choose between Hable and AMPAS.

Gamma – Specifies the gamma correction. It is applied before the operator.

Hable

Shoulder strength –  Determines how sharp the shoulder is. Higher values sharpen the shoulder, which results in an overall brighter image.

Linear strength – Determines the strength of the effect from changing Linear angle.

Linear angle –  Determines the angle of the curve at the base. Higher values increase the angle.

Toe Strength –  Low to mid tone compression. Higher values darken the low and mid tones.

White point – The intensity, which gets mapped to 1. This parameter scales the whole curve evenly.

AMPAS

AMPAS mode applies an approximate ACES standard curve.

LUT – Applies a lookup table file to the scene.

Amount – Specifies the LUT weight, where 0 is no LUT effect and a value of 1.0 applies fully the effect.

Load LUT file... – Loads a LUT (lookup table) file. See the LUT Preset example below.

Color space – Specifies the color space for the loaded LUT file. See the LUT Color Space example below.

Linear – The loaded LUT file is interpreted in linear color space.
sRGB – The loaded LUT file is interpreted in sRGB color space.
V-Ray Log. – The loaded LUT file is interpreted in a V-Ray logarithmic color space.

Size – Specifies the size of the filter as percentage of the image's diagonal.

Intensity – Multiplier for the bloom/glare source bright pixels. Increasing the value can boost the effect by simulating up to 20 times brighter source. Values lower than 1 can be used to produce subtle bloom/glare from overbright sources. 

Bloom – Controls the blend between bloom and glare. A value of 1 forces bloom to be applied to full extent and without any glare. A value of 0 removes the bloom completely and applies only glare. Values in-between blend the two effects proportionally.

Threshold – Sets a minimum value for the rendered pixels to be considered as lens effects source. The Bloom/Glare effect is generated only regarding pixels with larger value than the specified threshold.

Rotation – Rotates the final result, whether it is a filtered image or a procedurally created one.

Saturation – When the value is set to 0, the effects use the original hue of the bright pixels to create bloom and glare. Larger values intensify the hue set with the Cold/Warm option. 

Cold/Warm – When enabled, the Bloom/Glare effect is toned to cold hues. When disabled, the effects receive warm hue. The hue shift requires Saturation values larger than 0.

Blur / Sharpen – Applies blurring/sharpening effect to the scene.

Blur Radius – Determines the radius in pixels used for blurring. Higher values lead to greater blurring effect. Zero disables the blur effect.

Sharpen Radius – Determines the radius in pixels used for sharpening. Requires a non-zero value. Higher values lead to more extensive sharpening.

Sharpen Amount – Applies sharpening to the image. Increasing the amount leads to a sharper image, while setting the amount to 0 switches off this filter.

Hue / Saturation – Applies HSL transformation on the image colors.

Hue – Changes the overall hue of the image colors (grey colors remain intact).

Saturation – Specifies the image colors' intensities. Positive values produce a more vibrant, saturated image while negative values desaturate and dull the image colors.

Lightness – Adds or removes white from the image. Positive values add white to the image, making it lighter. Negative values remove white from the image, making it darker.

Color balance – Applies color balance adjustments:

All – Applies adjustments to the overall color tone of the image.
Highlights – Applies adjustments to the bright (highlight) colors of the image.
Midtones – Applies adjustments to the medium (midtones) colors of the image.
Shadows – Applies adjustments to the dark (shadow) colors of the image.

The color corrections are additive in that the All correction affects all colors of the image, and the Shadows/Midtones/Highlights options adjust the individual components in the image on top of the All correction.

Temperature – Adjusts the white balance of the image by specifying the color temperature in Kelvin. Lower values make the image bluer, higher ones make it more amber.

Magenta-Green tint – Adjusts the white balance of the image to make it greener (positive values) or more purple (negative values).

Color – Chooses a color to be the new "white point" for the image, adjusting all colors. Use it to pick a neutral color from the image (e.g. one that should be white or gray).

Chromatic Aberration – Applies a chromatic aberration effect to the scene. See the Chromatic Aberration example below.

Value – Specifies the amount of chromatic distortion from the center to the edges of the viewport. See the Chromatic Aberration example below.
