What is HDR (High Dynamic Range)?
HDR (High Dynamic Range) is an image format specifically designed to store a much wider range of luminosity than conventional image formats, allowing it to represent real-world lighting conditions more accurately.
Unlike standard 8-bit per channel formats that can represent only 256 levels per color channel, HDR files typically use 32-bit floating-point values that can represent an essentially unlimited range of brightness values.
The format is particularly valuable in 3D rendering, photography, and architectural visualization where accurately representing both very bright areas (like direct sunlight) and very dark areas (like deep shadows) in the same image is crucial.
HDR images are often created by merging multiple exposures of the same scene or through 3D rendering software that can generate physically accurate lighting simulations beyond the capabilities of standard display technology.
How to open HDR?
HDR files can be opened with professional imaging software like Adobe Photoshop (with HDR support), Affinity Photo, and specialized HDR editors like Luminance HDR.
3D rendering applications such as Blender, 3ds Max, and V-Ray have native support for HDR files, particularly for environment lighting and image-based lighting techniques.
For viewing purposes, specialized HDR viewers like HDRView, Picturenaut, and HDR Shop can correctly display the full dynamic range with tone mapping options.
Photography applications like Adobe Lightroom and Capture One can import and process HDR files, offering tools to map the high dynamic range to standard displays while preserving detail in highlights and shadows.
HDR is Developed by: Greg Ward (Radiance RGBE format)
HDR was Released on: Early 1990s

How to convert HDR?
To convert HDR files to standard dynamic range formats like JPEG or PNG, use our online HDR converter that applies intelligent tone mapping to preserve both highlight and shadow details.
For professional results, applications like Adobe Photoshop and Affinity Photo provide advanced tone mapping options to convert HDR to standard formats while maintaining visual impact.
When converting between different HDR formats (such as from Radiance HDR to OpenEXR), specialized tools like Luminance HDR or professional 3D software can maintain the full dynamic range information.
For web presentation, consider converting HDR content to formats that support HDR displays through technologies like HDR10 or Dolby Vision, though this requires special encoding processes beyond simple format conversion.
