CLIP
CLIP Strengths
- SQLite backend provides incredibly robust data integrity, preventing catastrophic project loss if the application crashes during a save
- Allows for massive multi-page comic projects and animation timelines to be handled efficiently without loading the entire project into RAM simultaneously
- Industry standard for manga, anime, and webtoon professional workflows
Limitations
- Heavily closed-source and proprietary, meaning no third-party applications (like ImageMagick or GIMP) can parse or render the files
- Standard MIME identification tools will misidentify the file as a generic SQLite database, causing friction in automated file-upload validations
- Zero web browser support
Olympus-ORF
Olympus-ORF Strengths
- Retains maximum sensor data, allowing extreme recovery of highlights and shadows that would be permanently lost in a JPEG
- White balance, sharpening, and color profiling are saved as metadata instructions, meaning they can be completely altered in post-production
- Unique magic byte signatures make programmatic file sniffing highly reliable compared to other camera manufacturers' TIFF-spoofing headers
Limitations
- Proprietary format means it requires constant updates to raw processing engines every time a new camera model is released
- Produces very large file sizes (often 15MB to 30MB+ per image depending on sensor resolution)
- Cannot be directly embedded into web pages or used in standard HTML/CSS contexts
