An HDR file stores images with a much wider range of brightness and color than standard image formats. It captures more detail in both very bright highlights and dark shadows, making images look more realistic and closer to what the human eye sees. HDR files are widely used in photography, visual effects, 3D rendering, and gaming.
Unlike regular images, HDR files contain high bit-depth data, which allows advanced color correction and lighting adjustments during post-processing.
HDR files can be opened with professional and advanced image tools, including:
Adobe Photoshop
Adobe Lightroom
GIMP
Affinity Photo
XnView MP
HDR-specific viewers and 3D software
On most systems, standard photo viewers may not display HDR correctly without tone mapping.
Because HDR files are large and not web-friendly, they are often converted to:
HDR → JPG
HDR → PNG
HDR → EXR
Conversion applies tone mapping to preserve visual detail in standard formats.
Developed for: High-end imaging and rendering
Initial use: Photography & computer graphics
