High Dynamic Range Images


A High Dynamic Range Image lets you store pixel information as floating values which provides a great deal more information about lighting in the scene. Using a real-world camera, this kind of information would be creating by taking pictures use different exposures at different shutter speeds. In Houdini you simply have to turn on specific Mantra setting.


Setting your Render Output for HDR

Set up a Render Output Operator for rendering out a sequence of images. Click on the [+] button next to the Render Command. Under the standard tab, scroll down to Quantization and turn it on. Make sure it is set to Floating point channels and Accept these settings.

Now your renderings will contain floating point values.
