Converting an image file to OpenEXR format will not add new information that wasn't already in the original file. If you convert a JPEG file to OpenEXR, then you can change the exposure within the viewer, but you won't see anything that you couldn't see by viewing the JPEG image directly. OpenEXR is a file format, not an image enhancement tool.
Most of the OpenEXR sample images were generated by combining multiple exposures. A few images were shot with a special high-dynamic-range camera; the rest are computer-generated.

Hi,
This is a quote on the OpenEXR page :
"You can reveal more detail in OpenEXR images by changing the exposure using the Exposure slider."
My question is if I take one photo and then adjust the exposure within the OpenEXR viewer can I create "real" HDRI images without taking multiple photos? Or will this not capture the full dynamic range like taking a traditional HDRI.
Thanks,
