canon-cr3
canon-cr3 Strengths
- Maintains 14-bit uncompressed sensor data, offering massive flexibility for recovering shadows and highlights in post-production
- The new C-RAW format offers roughly 40% smaller file sizes than uncompressed raw with virtually indistinguishable quality loss
- Utilizes the modern and extensible ISOBMFF container, moving away from archaic TIFF limitations
Limitations
- Being a proprietary format, it requires frequent software updates to third-party editing tools (like Lightroom or Capture One) every time a new camera model is released
- Completely unsupported in web browsers and standard operating system image viewers without specialized raw codecs
- Larger file sizes than in-camera JPEGs, requiring more storage space and processing power
JPEG
JPEG Strengths
- Universal support — every browser, OS, and application handles JPEG
- Excellent compression for complex photographs with natural color gradients
- Rich metadata support: EXIF (GPS, camera settings), ICC color profiles
Limitations
- No transparency — cannot have a transparent background
- Lossy compression introduces visible artifacts on sharp edges and text
- No animation support
