What is RAW?

Camera RAW is a file format containing unprocessed sensor data captured directly from a digital camera sensor, providing maximum flexibility for professional photo editing.

What is RAF?

Fujifilm Raw Format (RAF) contains raw sensor data from Fujifilm X-Series and GFX cameras with unique X-Trans sensor processing.

When Should You Use RAW vs RAF?

RAW vs RAF: Key Differences

• •RAW uses lossless compression while RAF 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.
• •How transparency is handled: RAF supports transparency, so alpha information is preserved during conversion.
• •File sizes: RAW files typically range 20-50MB per photo depending on camera and RAF files 20-50MB per photo.
• •Use case fit: RAW targets professional photography, post-processing, editing and RAF targets fujifilm photography, film simulation processing — your choice depends on which workflow stage you are serving.

Advantages of RAW

• ✓At its core, RAW relies on lossless encoding — a design choice that makes it perfect for Professional photography, post-processing, editing.
• ✓You won't run into compatibility issues with RAW — it's a universal standard across platforms.
• ✓File size management with RAW: larger files guaranteed to match the original exactly.
• ✓Every major application in the Professional photography, post-processing, editing space supports RAW natively.

Industry Applications

Best Practices for RAW to RAF Conversion

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

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