Understanding TIFF and HDR Formats

Learn about the source and target file formats to understand what happens during conversion.

Source Format

TIFF Image

image/tiff

TIFF (Tagged Image File Format) is a flexible, high-quality raster image format widely used in professional photography and publishing. It supports multiple compression methods including LZW and ZIP lossless compression, as well as uncompressed storage, and can store images with very high bit depths. TIFF also supports multiple pages, layers, and extensive metadata within a single file.

Advantages

  • Supports lossless compression and very high bit depths up to 32-bit per channel
  • Capable of storing multiple pages and layers in a single file
  • Widely accepted in professional print and publishing workflows

Limitations

  • Large file sizes even with compression enabled
  • Not natively supported by web browsers for display
  • Complex specification leads to inconsistent support across software

Common Uses

  • Professional photography and print production
  • Scanned document archival and storage
  • Medical and scientific imaging

Target Format

Radiance HDR Image

image/vnd.radiance

HDR (High Dynamic Range) Radiance format, also known as RGBE, stores images with a high dynamic range of luminance values using a run-length encoded format. Developed by Greg Ward for the Radiance lighting simulation system, it encodes each pixel as three 8-bit mantissas and a shared 8-bit exponent. HDR images capture a much wider range of brightness than standard 8-bit formats.

Advantages

  • Captures a wide dynamic range of lighting from very dark to very bright
  • Relatively compact encoding for high dynamic range data
  • Widely supported in 3D rendering, game engines, and compositing software

Limitations

  • Lower precision than 32-bit EXR for demanding visual effects work
  • Not suitable for direct display without tone mapping
  • Limited to RGB data with no alpha channel support

Common Uses

  • Environment maps and image-based lighting in 3D rendering
  • HDR photography merging and tone mapping workflows
  • Lighting simulation and architectural visualization
