Opening HDR files

Did your computer fail to open a HDR file? We explain what HDR files are and recommend software that we know can open or convert your HDR files.

What is a HDR file?

HDR is an acronym for High Dynamic Range. Files that contain the .hdr file extension, also referred to as HDRI or Radiance HDR files, are raster image files that have been saved in the HDR image format.

The HDR image format can be used to enhance the brightness and color of digital images using a compatible software program. This file format is commonly used to correct shadows and washed out areas within a picture that has been taken with a digital camera. Adobe Photoshop and Photomatix are applications that commonly use the HDR file format for images that have been edited within the software applications.
