Overview

 

Modifies the brightness of an environment map or other image in a way that is equivalent to having originally photographed it with different camera settings.

 

 

Exposure Sample

Because Genetica works with high dynamic range images, the Exposure node can

reveal detail that appeared to be lost, such as the blown-out clouds in the left image.

 

 

 

Inputs

 

This node's only input provides the original image that is to have its exposure adjusted.

 

 

 

Properties

 

 

Property

Description

Exposure

Brightens or darkens the image in a way that imitates changing the exposure setting on a camera.

Gamma

Modifies the relative brightness of different parts of the image using a gamma curve.  This property can help simulate the response to light that different cameras and display devices have.
