HDRDateiformate

HDRDateiformate refers to a class of digital file formats designed to store high dynamic range images, capable of representing luminance levels beyond standard 8-bit-per-channel images. They typically store 32-bit floating point or fixed-point data per color channel and include metadata about color space and tone mapping.

Prominent formats include Radiance HDR (.hdr, .pic) using RGBE encoding; OpenEXR (.exr) from Industrial Light & Magic with multi-channel data, multiple compression schemes, and both half and floating point precision; TIFF variants with 32-bit floating point per channel; and JPEG-HDR or JPEG XT extensions to extend JPEG with HDR capabilities while maintaining broader compatibility.

Character of formats: OpenEXR is favored in visual effects and animation for deep data and extensive metadata; Radiance HDR remains common in still photography and some tools; TIFF HDR variants integrate with existing TIFF workflows.

In practice, the choice depends on file size, compression, multi-channel support, software pipeline compatibility, and whether data is scene-referred or display-referred. HDRDateiformate thus describes a family of formats used in photography, graphics, and film production to preserve dynamic range before processing and display.
