Opening steps
Choose your environment or purpose to see its steps.
Menu labels and support vary by app, OS and version. Preserve the original before making changes.
Troubleshooting by symptom
- CR2 opens but CR3 fails: verify both format and camera support.
- Unclear RAW/C-RAW type: inspect capture settings rather than inferring them from the suffix.
- Missing special processing: check camera-feature support separately from basic decoding.
- Only a new camera’s CR3 fails: check updates and the camera table; general CR3 support is insufficient.
- Burst handling is unclear: consult camera/software documentation for special recording modes.
- Preview works but export fails: verify full RAW support and transfer completeness.
CR3 → JPEG / TIFF / supported DNG
- Develop and export separate JPEG/TIFF files, reviewing exposure, color and resolution.
- For DNG, verify converter camera support and compatibility before producing a copy.
- Inspect the rendered image at actual size for color, exposure, orientation and dimensions; preserve the RAW and adjustments.
Renaming CR3 to CR2 does not convert it. Retain the original for manufacturer-specific workflows.
New cameras and special modes
Search support tables by camera model. Features can differ by mode and application version even within CR3.
For important shoots, verify all files import and test several exports before organizing card originals.

When a recipient cannot open the RAW
For editing, include camera information and app requirements; for viewing, provide a rendered image.
Review disclosure of capture/location data and separate public copies from RAW storage.

Related-format differences
| Format | Main role | Selection notes |
|---|---|---|
| CR3 | Photographic development / storage | Check camera and recording-mode support |
| JPEG | Readily viewable sharing copy | Does not retain RAW adjustment flexibility |
| TIFF | Editing / printing after development | Check size, depth and color |
Handling and security
Review metadata and depicted individuals before publication; follow the permitted scope for cloud sharing.
Questions and answers
Does C-RAW always have another suffix?
Supported cameras use CR3; inspect capture settings or application metadata.
Why does a new camera’s CR3 fail?
Check which software version added that camera.
Is CR2 support sufficient?
No; CR3 and exact-camera support are separate requirements.
Can C-RAW also use CR3?
Supported cameras can use CR3 for C-RAW. Inspect capture information for mode/compression rather than relying on the suffix.
Is CR3 a video?
The Canon CR3 discussed here is for RAW stills. Camera video has separate format/support requirements.
