RAF (camera RAW)

What is an RAF (camera RAW) file?

The RAF extension identifies a raw image file generated by Fujifilm digital cameras. It contains unprocessed data directly from the camera's image sensor-typically Fujifilm's proprietary X-Trans CMOS or standard Bayer filter arrays-along with a JPEG preview and Exif metadata. The file structure encapsulates the sensor's exact luminance values and color information before demosaicing or gamma correction is applied. This format allows for extensive post-processing flexibility regarding white balance, exposure, and color grading compared to compressed formats.

How to open an RAF (camera RAW) file

To view or edit RAF files, users require software capable of interpreting the specific sensor data mapped in the file header. Fujifilm provides 'Fujifilm X RAW STUDIO' for native processing. Industry-standard applications such as Adobe Lightroom Classic, Capture One, and the open-source RawTherapee support RAF decoding. Microsoft Windows users may need to install the 'Raw Image Extension' package, while macOS Preview possesses built-in support for most RAF iterations via Apple's Core Image framework.

AVIF

What is an AVIF file?

The AVIF (AV1 Image File Format) is an open, royalty-free raster image container specified by the Alliance for Open Media (AOMedia) in ISO/IEC 23000-12. It encapsulates image sequences or still images compressed with the AV1 video codec within the HEIF (High Efficiency Image File Format) container structure. AVIF supports high dynamic range (HDR) utilizing Perceptual Quantizer (PQ) or Hybrid Log-Gamma (HLG) transfer functions, wide color gamut (WCG), and 4:2:0, 4:2:2, or 4:4:4 chroma subsampling, offering superior compression efficiency over JPEG and WebP.

How to open an AVIF file

Native support for AVIF is available in modern web browsers including Google Chrome (v85+), Mozilla Firefox (v93+), and Safari (v16+). For local viewing, Windows 10 and 11 require the installation of the free 'AV1 Video Extension' from the Microsoft Store to enable support in the Photos app and File Explorer. macOS 13 (Ventura) and iOS 16 provide system-level support. Graphics editors like GIMP, Paint.NET, and Adobe Photoshop (via plugin) can also decode and edit these files.

RAF to AVIF

Why convert RAF to AVIF?

RAF is an unprocessed sensor data format and AVIF is a lossy or lossless format. AVIF supports transparency; RAF doesn't.

Turn a RAW photo into a finished image

RAF is unprocessed sensor data straight from the camera. Converting to AVIF develops it into a normal image with the camera's colors applied, ready to share, print or post.

Much smaller files

AVIF can use lossy compression, so the file is usually a fraction of the RAF size, which is quicker to email, upload and load on a website.

Ready for transparency

AVIF supports transparent backgrounds. Convert first, then remove the background or layer the image over other graphics.

Faster websites

AVIF gives smaller files than JPG or PNG at the same visual quality, which makes pages load faster and can help Core Web Vitals and SEO.
