Opening OpenEXR Files
Any command that opens an image file, such as View Image File > Specify an
EXR file. > Click Open. > OpenEXR Configuration dialog
This version of the OpenEXR Configuration dialog appears whenever you
open an EXR file. It lets you specify various color transformations to be applied
to the loaded image, designate the internal storage format to use, and preview
the loaded image with the color transforms applied. There is also a histogram
for viewing the brightness distribution in the image and adjusting the white
and black points interactively.
