Kisahnya

BAGAIMANA CR3
TERCIPTA.

CR3 shipped in May 2018 with the Canon EOS M50, replacing CR2 after 14 years as Canon’s native raw format. The structural change is significant: where CR2 was a TIFF variant with Canon's own IFD tags, CR3 uses the ISO Base Media File Format container — the same as MP4 and HEIF. Canon also introduced C-RAW, a lossy-compressed raw variant that ships inside CR3 at 40% smaller file sizes than the full CRAW lossless.

Every Canon EOS R mirrorless body, every late-cycle DSLR since 2018, every Cinema EOS C70/C80, and every mainstream EOS M/RP/R5/R6 writes CR3. A decade-plus of CR2 archives still exists in professional libraries, but CR3 is the active format. Canon still doesn’t publish the spec — like CR2, every third-party raw processor has reverse-engineered the internal layout.

FAKTA UNIK &
TRIVIA.

CR3 was Canon's first major raw-format change in 14 years — CR2 ruled from 2004 to 2018.

C-RAW (lossy compressed RAW, inside a CR3 container) cuts file sizes by ~40% with perceptually equal quality — a real middle ground for photographers who shoot bursts.

CR3 uses ISO Base Media File Format (same as MP4/HEIF) — a radical break from CR2's TIFF lineage.

Canon still does not publish the CR3 spec — Lightroom, Capture One, and Darktable all reverse-engineered it.

The EOS R5's 45 MP CR3 files are typically 45-55 MB; in C-RAW, closer to 30 MB — cuts a day's shoot from 30 GB to 18 GB.

KEUNGGULAN &
KETERBATASAN.

Keunggulan

Modern ISO Base Media File Format container.
Supports lossless + compressed C-RAW in the same extension.
Preserves every pixel of Canon mirrorless sensors.
Compatible with Canon's cross-camera pipeline (DPP, Cinema EOS).

Keterbatasan

Proprietary — no public spec.
Third-party support is always playing catch-up with each new body.
Older Canon processing software (DPP 4) does not read CR3.
File sizes remain large — 45+ MB per shot on flagship bodies.
