# 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             | Enable the Glow & Glare.                                                                                       |
| ------------------- | -------------------------------------------------------------------------------------------------------------- |
| Force High Quality  | Increases the internal resolution for more detailed calculation. This option is heavy on the GPU!              |

| 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.&#x20;

| 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.
{% endhint %}
