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

When Should You Use CUR vs 3FR?

CUR vs 3FR: Key Differences

• •CUR uses lossless compression while 3FR uses lossless compression — both take the same approach to file size management.
• •Neither format changes compression philosophy — both are lossless compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
• •Alpha channel support: 3FR lacks transparency support.
• •File sizes: CUR files typically range Very small, typically under 50KB and 3FR files 40-80MB per image from medium-format sensors.
• •CUR is optimized for windows ui cursors, mouse pointer graphics while 3FR is designed for medium-format photography, professional studio — choose based on your specific workflow needs

Advantages of CUR

• ✓At its core, CUR relies on lossless encoding — a design choice that makes it perfect for Windows UI cursors, mouse pointer graphics.
• ✓You won't run into compatibility issues with CUR — it's a universal standard across platforms.
• ✓File size management with CUR: larger files guaranteed to match the original exactly.
• ✓Every major application in the Windows UI cursors, mouse pointer graphics space supports CUR natively.

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.

Industry Applications

Best Practices for CUR to 3FR Conversion

• →Before converting CUR to 3FR, 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 3FR — you cannot recover detail lost during lossy compression
• →Check the color profile: CUR images may use a wider gamut than 3FR 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 CUR to 3FR Conversion

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