Converting an OpenEXR Image in the LUT Editor
ImportantThe PhotoMap tool is the recommended method for OpenExr conversion in Flame. The EXR Display tool is provided mostly for legacy workflows.

You can convert the output of an OpenEXR image by accessing EXR Display controls in the LUT Editor.

To convert an OpenEXR file:

1. Access the LUT Editor. See Accessing the LUT Editor.
2. From the Conversion LUT Type box, select EXR Display.

   The EXR Display controls appear.

   Exposure
     Enter the display image exposure. Editing this value lightens or darkens the display image, revealing detail in the high or low range of luminance.
   Defog
     Subtract from pixel values to reduce fogging of the image.
   Knee Low
     Set the lower limit of a compressed pixel range. The knee function determines the white point and middle grey values of the image.
   Knee High
     Set the upper limit of a compressed pixel range. The knee function determines the white point and middle grey values of the image.
   Gamma
     Enter the gamma correction values for your screen setup.
   P (Proportional)
     Enable to change remaining channel values proportionally with respect to a selected value.
3. In the Destination menu, select the output bit depth.
