When Should You Use IIQ vs 3FR?

IIQ vs 3FR: Key Differences

• •IIQ and 3FR diverge on compression: lossless compression for the source, lossless compression for the target.
• •Since both IIQ and 3FR use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •Transparency: N/A
• •IIQ files are typically 50-150MB per image from medium-format backs while 3FR files range 40-80MB per image from medium-format sensors
• •Primary audience: IIQ is built for professional studio photography, digital back capture scenarios, while 3FR focuses on medium-format photography, professional studio — pick the format that matches your output requirement.

• ✓IIQ is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Advantages of 3FR

• ✓3FR compresses data using lossless methods, keeping file sizes manageable for Medium-format photography, professional studio.
• ✓Industry-wide support means 3FR files open anywhere — from legacy systems to the latest devices.
• ✓Lossless quality makes 3FR the gold standard for archival and master copies.
• ✓From Adobe Photoshop to open-source alternatives, 3FR works out of the box.

Troubleshooting IIQ to 3FR Conversion

• !3FR shows visible compression artifacts → lower the compression level or switch to a lossless variant
• !The converted 3FR image looks washed out → the source IIQ likely uses a wider color space than 3FR supports
• !3FR file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
• !Text in the converted 3FR looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
