What is hdr file? How to open hdr files?
File type specification:
The hdr file extension is also related to Photomatix software and used for its default HDR image format.
In image processing, computer graphics, and photography, high dynamic range imaging (HDRI or just HDR) is a set of techniques that allows a greater dynamic range of exposures (the range of values between light and dark areas) than normal digital imaging techniques. The intention of HDRI is to accurately represent the wide range of intensity levels found in real scenes ranging from direct sunlight to shadows.
Also used for another image formats like Apollo HRDU, Analyze from Mayo Foundation Biomedical Imaging Resource etc. Probably unrelated, just sharing same extension and file type.
