RAF vs DJVU Format Comparison
| Aspect | RAF (Source Format) | DJVU (Target Format) |
|---|---|---|
| Format Overview |
RAF
Fujifilm RAW Format
Fujifilm's proprietary RAW format storing unprocessed 14-bit sensor data from X-Trans and Bayer CFA sensors. RAF captures the unique color rendition and film simulation data that define Fujifilm's renowned color science. Lossless RAW |
DJVU
DjVu Document Format
A wavelet-compressed document format from AT&T Labs using IW44 compression with intelligent foreground/background separation, achieving extreme compression for scanned documents and image-heavy content. Lossy Standard |
| Technical Specifications |
Color Depth: 14-bit per channel (X-Trans/Bayer) Compression: Lossless compressed Transparency: Not supported Animation: Not supported Extensions: .raf |
Color Depth: 24-bit RGB Compression: IW44 wavelet + JB2 text Transparency: Mask layer Multi-page: Bundled documents Extensions: .djvu, .djv |
| Image Features |

| Processing & Tools |
RAF requires specialized processing with X-Trans demosaicing for optimal quality.
# Fuji X Raw Studio (official)
# Lightroom / Capture One
# rawpy with X-Trans support
import rawpy
raw = rawpy.imread('photo.raf')
rgb = raw.postprocess(output_bps=16)

Why Convert RAF to DJVU?
Fujifilm RAF files range from 30-70 MB each, making large collections impractical for storage and sharing. Converting to DJVU applies wavelet compression that reduces these files to under 1 MB while preserving the visual character of Fuji's renowned color rendition for reference viewing and archival.
Street photographers and documentarians who shoot extensively with Fujifilm X-series cameras accumulate thousands of RAF files. Converting processed selections to DJVU creates compact, browsable photo essays and project archives that can be shared via email or stored on mobile devices.
DJVU's multi-page capability is particularly useful for Fujifilm photographers who shoot in series. Wedding coverage, event documentation, or travel photo essays can be compiled into single navigable files with thumbnail page browsing.
The conversion renders RAF data through standard demosaicing, producing the neutral camera rendering. Fujifilm's film simulation effects (Classic Chrome, Velvia, etc.) embedded in the RAF metadata are not applied during conversion. For film simulation rendering, process in Fuji X Raw Studio or Capture One first.
Key Benefits of Converting RAF to DJVU:
- Massive Compression: 50 MB RAF files become sub-megabyte DJVU documents
- Photo Essay Compilation: Bundle street photo series into browsable documents
- Client Delivery: Compact proof packages from wedding and event shoots
- Travel Albums: Create portable photo journals from Fuji travel captures
- Storage Efficiency: Archive thousands of processed photos compactly
- Progressive Viewing: Quick preview browsing of large collections
- Universal Access: View without RAW processing software
Practical Examples
Example 1: Street Photography Zine
Scenario: A street photographer compiles a series shot on Fuji X100V into a digital zine for distribution to photography communities.
Source: tokyo_streets_*.raf (40 files, X100V, ~1.2 GB) Target: tokyo_streets_zine.djvu (40 pages, ~6 MB) Result: Digital photo zine in 6 MB, shareable via email or community forums, with page navigation for the curated street photography sequence.
Example 2: Wedding Photography Proofs
Scenario: A wedding photographer needs to send 500 proof images from an X-H2 shoot for the couple to review and select prints.
Source: johnson_wedding_*.raf (500 files, X-H2, ~18 GB) Target: johnson_wedding_proofs.djvu (500 pages, ~85 MB) Result: Complete wedding proof set in 85 MB browsable document, downloadable over home internet, viewable on any device for print selection.
Example 3: Landscape Portfolio Archive
Scenario: A landscape photographer archives their best X-T5 captures from a year of shooting into a compact portfolio reference.
Source: best_of_2025_*.raf (150 images, X-T5, ~6.5 GB) Target: landscape_portfolio_2025.djvu (150 pages, ~32 MB) Result: Year's best work in 32 MB portfolio document, browsable with thumbnails, suitable for gallery submission and personal archive reference.
Frequently Asked Questions (FAQ)
Q: Are Fujifilm film simulations applied during conversion?
A: No. The conversion uses neutral demosaicing. Film simulation metadata (Classic Chrome, Velvia, etc.) is not applied. To preserve film simulation looks, process RAF files in Fuji X Raw Studio or Capture One first, then convert the output to DJVU.
Q: Does the converter handle X-Trans sensor RAF files?
A: Yes. Both X-Trans CFA (unique 6x6 pattern) and traditional Bayer CFA RAF files from all Fujifilm cameras are supported, including the latest X-Trans V sensors in X-T5 and X-H2.
Q: How much compression will I see from RAF to DJVU?
A: Typically 50-100x compression. A 50 MB X-T5 RAF file typically becomes 500 KB to 1 MB as DJVU. Complex landscape scenes compress less aggressively than uniform studio shots.
Q: Will the 14-bit dynamic range be preserved?
A: No. DJVU reduces to 8-bit per channel with lossy compression. The extended highlight and shadow recovery latitude is lost. Keep original RAF files for reprocessing needs.
Q: Is DJVU suitable for client delivery of Fuji photos?
A: For proof review and selection purposes, yes. DJVU provides excellent visual quality at compact file sizes. For final print delivery, use TIFF or JPEG at full resolution instead.
Q: Can I include captions or EXIF data in the DJVU?
A: DJVU supports text annotations and metadata per page. EXIF data from RAF files is not automatically transferred, but can be added as DJVU annotations using djvused after conversion.
Q: Which Fujifilm cameras produce RAF files?
A: All Fujifilm digital cameras with RAW capability: X-series (X-T5, X-H2, X-Pro3, X100V, etc.), GFX medium format series, and older FinePix models. All RAF versions are supported by the converter.
Q: Can I convert compressed RAF (lossy RAW) files?
A: Yes. Both lossless and lossy compressed RAF files are supported. The DJVU output quality depends on the visual content rather than the RAF compression mode.
