富士フイルムのカメラが捉えたRAFファイル。その豊かな色情報と広いダイナミックレンジは、写真愛好家やプロの現場で高く評価されています。しかし、映像制作やVFXのワークフローでは、より広範な互換性と高精度な画像処理が求められる場面が少なくありません。そこで登場するのが、OpenEXR（EXR）です。EXRは、非破壊編集に強く、多層画像や32ビット浮動小数点の色深度をサポートすることで、RAWデータが持つ可能性を最大限に引き出します。本ページでは、RAFファイルをEXR形式へ変換する意義と、その具体的な手順について詳しく解説します。あなたの作品が、より多くの表現力を手に入れるための一助となれば幸いです。
- アニメ・VFX制作における素材連携
- 高精度なHDR画像編集
- 商業印刷向けの色深度保持
日本の映像業界では、アニメーション制作における多層合成や、ゲーム開発でのHDR環境マップ生成において、EXR形式が標準的なフォーマットとして広く採用されています。RAFからの変換は、これらの制作現場でRAWデータを活用する上で重要な工程となります。
About RAF (FUJIFILM) to OPENEXR Conversion
RAF (introduced 2003) and EXR (introduced 2003) are both image formats, but they differ in important ways. RAF is Fujifilm's RAW photo format, preserving the X-Trans or Bayer sensor data. EXR (OpenEXR) is a high-dynamic-range format used in VFX, film, and 3D rendering pipelines.
Full Name: RAF uses Fujifilm RAW, while EXR uses OpenEXR Image. Compression: RAF uses Lossless, while EXR uses Lossy & Lossless. Transparency: RAF uses No, while EXR uses Yes.
When you convert RAF to EXR, the goal is to convert between formats quickly. Converting RAF to EXR maintains high quality with CocoConvert's optimised encoder settings. Understanding these technical differences helps you choose the right format for your workflow.
Your RAF file is decoded and re-encoded as EXR. The conversion involves 4 steps: (1) your raf file is uploaded and the format is validated, (2) the file content is decoded into its raw representation, (3) the data is re-encoded in exr format with optimal settings, (4) the converted file is ready for download.
CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.
This conversion is ideal when you When you specifically need a EXR file for your workflow. For the opposite direction, CocoConvert also supports EXR to RAF conversion.

What Happens When You Convert RAF (FUJIFILM) to OPENEXR
Your RAF image is decoded into raw pixel data, then re-encoded as EXR.
Your RAF file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
Pixels are re-encoded using OpenEXR Image's lossless compression
Metadata (EXIF, ICC profiles) is transferred where EXR supports it
The EXR file is saved and ready for download
