High Dynamic Range Image (HDRI) Export

When RenderWorks is installed, the HDRI option is added to the list of export file choices. This command creates an OpenEXR file. This is a good choice for export when touching-up the image in an imaging program; the exported image is “lossless” and will not have quantization artifacts when color or exposure is further adjusted after export.

To export a file in HDRI format:

1.	Select the RenderWorks rendering mode to use for the export, and render the image.

2.	Select File > Export > Export High Dynamic Range Image (HDRI).

The Export HDRI dialog box opens. Specify the dimensions and resolution for the exported image.
