# Post-FX
The following settings are available for Post-FX:
## **Lens**
| Chromatic Distortion | Creates a chromatic abberation effect. |
| -------------------- | ---------------------------------------------------- |
| Glow | Intensity of Glow. |
| Glow Threshold | Threshold at which intensity glow should be applied. |
| Lense Flare | Simulates a lens flare on very bright parts. |
| Dirt Lense | Multiplies a dirt effect into the glow. |
### Glow & Glare
The Glow & Glare feature is an advanced extension to simulate the aperture diffraction of real camera lenses or the usage of additional filters, also called "star-filter". This effect drastically increases photorealism, while giving a better feeling for intensities.
The sensitivity and intensity of the effect depend on the Glow & Glow Threshold values. To simulate different filters and apertures, some presets can be chosen or used custom.
Enabled Glow & Glare
Without
| Enabled | Enable the Glow & Glare. |
| ------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Force High Quality | Increases the internal resolution for more detailed calculation. This option is heavy on the GPU! |
| Presets |
Aperture & Filter presets. Select custom for more:
|
| *Custom Properties* | |
| Blade Count | Aperture blades. |
| Blade width | Spread of the Bursts. |
| Glare | Fade between Burst and Glow. |
| Glare fx1, fx2 | Math function to define the falloff. |
| Glare intensity | Output intensity. |
| Rotation | Burst rotation. |
| Threshold | Additional input threshold. |
## **Tone Mapping**
While Depence renders in HDR *(High Dynamic Range)* values, the Tone-Mapper defines how HDR images get composed back into an LDR image.
The auto-exposure will detect the average intensity on the screen, and level the current Camera Exposure automatically.
Depence is working in a color space called ACEScg to provide a larger spectrum and simulate the behavior of real Cameras.
| Auto Exposure | Automatic exposure. |
| ----------------- | --------------------------------------------------------- |
| Color temperature | Adjust white balance. |
| Exposure | Offset to the current exposure. |
| Spectrum | Cuts the current hue shift caused by the ACES tonemapper. |
{% hint style="info" %}
While ACEScg looks most realistic, it can produce colors that aren't expected while programming a light-show. By using the Spectrum value it is possible to clamp the space to get back to plain sRGB values.
