| Format Overview |
CAP
Phase One Capture RAW
Phase One's early RAW format used by older Phase One digital backs before the transition to IIQ format. CAP files store unprocessed sensor data from Phase One's first-generation digital camera backs. Lossless RAW |
TIFF
Tagged Image File Format
A flexible professional format supporting multiple compression methods and color spaces. Lossless Standard |

Why Convert CAP to TIFF?
Converting CAP to TIFF transforms Phase One RAW camera data into Tagged Image File Format format. CAP files store unprocessed 14-16 bit RAW sensor data, and converting to TIFF makes your photos accessible on any device.
CAP files are typically 15-40 MB each. Converting to TIFF provides a universally compatible format while preserving the quality captured by your Phase One camera.
For photographers using Phase One cameras, converting CAP to TIFF is essential for sharing, publishing, and archiving images in a format that doesn't require specialized RAW software.
Our converter processes the raw sensor data through professional demosaicing algorithms, producing high-quality TIFF output optimized for professional workflows.
Key Benefits of Converting CAP to TIFF:
- Accessibility: Convert Phase One RAW to universally readable format
- Sharing: TIFF files can be viewed on any device
- Quality: Professional RAW processing preserves image detail
- Compatibility: TIFF works with standard image tools
- Workflow: Integrate Phase One photos into modern pipelines
- Storage: Reduce file size from 15-40 MB RAW originals
- Future-Proof: Convert to actively maintained format standard
Practical Examples
Example 1: Phase One Camera Photo Processing
Scenario: A photographer converts Phase One RAW files to TIFF for portfolio publication.
Source: portrait.cap (15-40 MB, 6-22 megapixels, 14-16 bit RAW) Conversion: CAP → TIFF Result: portrait.tiff ✓ Full RAW quality preserved in processing ✓ Compatible with modern platforms ✓ Portfolio-ready output ✓ Professional color accuracy
Example 2: Phase One RAW Archive Migration
Scenario: A photographer migrates Phase One RAW archives to TIFF for long-term preservation.
Source: landscape.cap (15-40 MB, 6-22 megapixels, 14-16 bit RAW) Conversion: CAP → TIFF Result: landscape.tiff ✓ Future-proofed in standard format ✓ Accessible without specialized software ✓ Quality preserved for long-term storage ✓ Modern format compatibility
Example 3: Batch Converting Phase One Photos
Scenario: A photographer batch converts CAP files from a Phase One camera to TIFF for client delivery.
Source: event_001.cap (15-40 MB, 6-22 megapixels, 14-16 bit RAW) Conversion: CAP → TIFF Result: event_001.tiff ✓ Fast batch processing ✓ Client-ready deliverables ✓ Professional quality output ✓ Universal device compatibility
Frequently Asked Questions (FAQ)
Q: What is the CAP format?
A: Phase One's early RAW format used by older Phase One digital backs before the transition to IIQ format. CAP files store unprocessed sensor data from Phase One's first-generation digital camera backs.
Q: Is CAP to TIFF conversion lossless?
A: The RAW processing step (demosaicing) is inherent to any RAW conversion. The TIFF output preserves the full quality of the processed image.
Q: Which Phase One cameras produce CAP files?
A: Phase One LightPhase, H20, H25, H5, H10, H101, and early Phase One digital backs.
Q: Why should I convert CAP files?
A: CAP files require specialized software to view and edit. Converting to TIFF ensures your photos are accessible on any device and in any application.
Q: Can I edit the CAP file before converting?
A: Our converter applies standard RAW processing (demosaicing, white balance, exposure). For advanced editing, use Capture One before converting.
Q: How large are CAP files?
A: CAP files are typically 15-40 MB depending on the camera model and sensor resolution (6-22 megapixels).
Q: What software supports CAP files?
A: Capture One, Adobe Lightroom, Phase One C1, dcraw. Our online converter requires no software installation.
Q: Are there file size limits?
A: Our converter handles CAP files of any size from Phase One cameras. Processing time depends on the sensor resolution.
