What is 3FR?

Hasselblad 3FR is a medium-format camera raw format used by Hasselblad digital cameras, preserving complete sensor data for professional post-processing.

What is HDR?

Radiance HDR is an image format that stores high dynamic range pixel data, commonly used for HDRI environment maps and lighting.

When Should You Use 3FR vs HDR?

Use 3FR When...

Reach for 3FR when your priority is medium-format photography, professional studio — its uncompromising quality ensures every detail is preserved.

Use HDR When...

Reach for HDR when your priority is hdri lighting, panoramic photography — its uncompromising quality ensures every detail is preserved.

3FR vs HDR: Key Differences

  • •3FR and HDR diverge on compression: lossless compression for the source, lossless compression for the target.
  • •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
  • •Transparency: N/A - HDR is for lighting data
  • •File sizes: 3FR files typically range 40-80MB per image from medium-format sensors and HDR files 5-30MB for typical HDR maps.
  • •3FR is optimized for medium-format photography, professional studio while HDR is designed for hdri lighting, panoramic photography — choose based on your specific workflow needs

Advantages of 3FR

  • ✓3FR applies lossless compression specifically calibrated for Medium-format photography, professional studio.
  • ✓3FR enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓3FR guarantees every bit of the original data survives — no approximations, no shortcuts.
  • ✓You will find 3FR support built into virtually every tool that handles Medium-format photography, professional studio — no plugins or converters needed.

Advantages of HDR

  • ✓HDR applies lossless compression specifically calibrated for HDRI lighting, panoramic photography.
  • ✓HDR enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓HDR guarantees every bit of the original data survives — no approximations, no shortcuts.

Best Practices for 3FR to HDR Conversion

  • →Before converting 3FR to HDR, decide whether you need maximum quality or smallest file size — this determines which format truly fits
  • →Save a master copy in a lossless format before converting to HDR — you cannot recover detail lost during lossy compression
  • →Check the color profile: 3FR images may use a wider gamut than HDR supports, causing a visible shift after conversion
  • →Resize images to the final display dimensions before converting — this avoids unnecessary processing of oversized files
  • →Run a single test conversion first to verify quality meets your standards
  • →Strip unnecessary metadata to reduce file size after conversion

Troubleshooting 3FR to HDR Conversion

  • !Converting 3FR to HDR gives blurry output → increase the quality setting before conversion
  • !Colors look different in HDR than 3FR → check color profile mismatch (sRGB vs Adobe RGB)
  • !File size changed more than expected → HDR uses different compression, file size differences of 2-5x are normal
  • !Transparent areas in 3FR turned white in HDR → HDR may not support transparency
