What is FFF?

FFF (image/x-hasselblad-fff) uses lossless compression optimized for medium format photography, hasselblad post-processing. Imacon/Hasselblad 3F RAW - Hasselblad digital back raw format

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 FFF vs HDR?

FFF vs HDR: Key Differences

• •FFF uses lossless compression while HDR uses lossless compression — both take the same approach to file size management.
• •Since both FFF and HDR use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •Transparency: N/A - HDR is for lighting data
• •Storage footprint: varies for FFF vs 5-30MB for typical HDR maps for HDR.
• •FFF is optimized for medium format photography, hasselblad post-processing while HDR is designed for hdri lighting, panoramic photography — choose based on your specific workflow needs

Advantages of FFF

• ✓FFF uses lossless compression tailored for Medium format photography, Hasselblad post-processing.
• ✓FFF is supported natively on virtually every device, browser, and operating system.
• ✓FFF files are bit-for-bit perfect, preserving every pixel and sample for professional work.
• ✓FFF integrates seamlessly with all major photo editing tools and workflows.

Advantages of HDR

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

Industry Applications

Best Practices for FFF to HDR Conversion

• →When converting FFF to HDR, check whether HDR supports transparency — if not, your transparent areas will be filled with a solid color
• →Use HDR for maximum quality archival and FFF for smaller file sizes when quality is less critical
• →Optimize images for web to reduce page load times — tools like our converter let you adjust quality settings before conversion
• →Maintain original aspect ratio to avoid distortion during conversion
• →Always keep a backup of your original files before converting
• →Choose the appropriate quality settings for your specific use case

Troubleshooting FFF to HDR Conversion

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