Alternate fog and Rayleigh scattering rendering.
For color tone adjustment SLIGHTLY change Green and Blue coefficients.

Parameter(s):
- Effect power: Higher power value = strong effect. Range: [1.00 .. 7.00]. Default: 2.50
- Density factor: Density factor allows to control the "density" of the effect. Higher factor value = strong effect. Range: [0.00001 .. 0.00099]. Default: 0.00010
- Color tone [Green]: Scattering efficiency of green light component. Range: [0.01 .. 0.99]. Default: 0.10

Tweak allows to reduce fog glowing effect at high altitudes during twilight.
Note: high values for Twilight level parameter may affect sky rendering during the day.
Different sky textures may require different settings.

Parameter(s):
- Twilight level: Twilight level at which the reducing starts. 0.00 is for night. Range: [0.01 .. 1.00]. Default: 0.20
- Reduction efficiency: The efficiency of glow reducing . 1.00 = max. effect Range: [0.1 .. 1.0]. Default: 0.2

Saturation allows to adjust the intensity of sky color.

Parameter(s):
- Saturation: When the saturation is 0.0, what you will see is a shade of gray. Range: [0.0 .. 2.0]. Default: 1.0

Terrain coloring filter that allows to adjust vegetation shades.
If you think the terrain should be more green and less khaki, try "Khaki correction". Filter will keep green as green and gray as gray, but khaki tone will be changed.
Many Ortho photos have typical emerald/bluish shade. If you are using Ortho textures "Bluish correction" parameter of the filter will help to restore the natural shade in such areas. Use it with "Red compensation" according to your preferences and textures.
"Red correction" parameter works only when "Bluish correction" is not equal 0.0.

Parameter(s):
- Khaki correction: Larger values mean stronger correction of khaki shade. Range: [0.1 .. 0.9]. Default: 0.3
- Bluish correction: Larger values mean stronger bluish shade compenation. 0.0 = no correction. Range: [0.0 .. 0.5]. Default: 0.4
- Red compensation: Larger values mean stronger red addition for bluish compensation. Range: [0.0 .. 3.0]. Default: 1.5

A cheap/fast imitation of the seasons by using special terrain coloring filters. May give some winter/spring/fall look and feel from altitude. Specific values of tweak parameters should be based on used type of textures (default/Ortho/ORBX/...). May have a mutual effect with khaki correction tweak. The tweak doesn''t affect buildings and aircrafts. Some scenery addons may use trees drawing in "autogen mode". These trees also remain unchanged by tweak.

Parameter(s):

- Wilting of vegetation level (for low snow levels). Range: [0.8 .. 1.5]. Default: 1.15

To add some post-processing effects at X-Plane global rendering stage activate the corresponding shaders in list below.
Activated effects will apply to whole scene in the sim.
This tweak works only in HDR mode.
IMPORTANT: To use post-processing, you SHOULD use antialiasing settings with activated FXAA mode (i.e. FXAA, 2x SSAA+FXAA, 4x SSAA+FXAA, etc.).
However, if you don't need FXAA, just use "FXAA is always off" switch.
To use post-processing, just check the appropriate effect in list and set the parameters specific to the shader.
The order of effects activation could be important and depends on the set. You can change the order with Up, Down buttons.
After applying the shader tweaks, the selected post-processing effects will be installed to X-Plane).
Use "Restore defaults" button to return to default settings for the selected post-processing effect.

Parameter(s):
- FXAA switch. Default state: ON

DPX (Cineon): should make the image look like it's been converted to DXP Cineon - basically it's another movie-like look similar to technicolor effect.

Brightness [0.5 .. 1.5]. Default 1.0. Higher means brighter image.
Saturation [0.0 .. 1.5]. Default 1.0. Additional saturation control since this effect tends to oversaturate the image.

Levels_white_point [0 .. 255] - the new white point. Everything brighter than this becomes completely white. Default is 235.0.

Parameters:
Vibrance [-1.00 .. 1.00] (default=0.2) saturates (or desaturates if you use negative values) the pixels depending on their original saturation.
Vibrance_RGB_balanceXYZ [-10.00 .. 10.00] - a per channel multiplier to the Vibrance strength so you can give more boost to certain colors over others. X=Red, Y=Green, Z=Blue

Tonemap: adjusts gamma, exposure, saturation, bleach and defog (may cause clipping).
Parameters:
Gamma [0.000 .. 2.000] - adjust midtones. 1.000 is neutral. This setting does exactly the same as the one in Lift Gamma Gain, only with less control. Default 1.000

Parameters:
Brightness [-1.0..1.0] default level is 0.0, contrast [0.0..2.0] default level is 1.0
When the saturation is 0.0, what you will see is a shade of gray. 1.0 is default level.

SharpenBlurring: slightly sharpen or blurring image.
Parameters:
Strength [-2.0 .. 2.0]. Use negative values to blur or positive for sharpen. Default value is 0.60.
This effect can be FPS hungry on weak hardware.

To add some post-processing effects at X-Plane internal view rendering stage activate the corresponding shaders in list below.
Activated effects will apply only to internal views and virtual cockpit.
To use post-processing, just check the appropriate effect in list and set the parameters specific to the shader.
You can also use expressions with some shader variables as parameter values.
The order of effects activation could be important and depends on the set. You can change the order with Up, Down buttons.
Internal stage post-processing effects will be installed to X-Plane and applied before global stage effects.
Use "Restore defaults" button to return to default settings for the selected post-processing effect.
