The Atmosphere Render Element stores only atmospheric or volumetric participating media such as Environment Fog or Aerial Perspective. This render element can then be used to enhance or color-correct just the atmospheric component of the image during the compositing process.

When atmospheric effects or fog is included in a scene, they will render into the Beauty (RGB color) channel, and should also be output as the atmosphere channel for compositing use.

Common Uses  

...

The Atmosphere Render Element is useful for changing the appearance of the atmosphere and volumetric effects in a rendered image using compositing or image editing software. In the example, fog is generated using the V-Ray EnvironmentFog. The fog is assigned a warmer color and the intensity is increased, using the Atmosphere RE.
