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

GIF

GIF Strengths

Universal support across all web browsers, operating systems, and messaging apps
Supports basic frame-by-frame animation out of the box
Lossless compression is highly effective for simple, flat-color graphics like logos or pixel art

Limitations

Limited to 256 colors per frame, resulting in poor quality for complex gradients and photographs
Animations produce massive file sizes compared to modern formats like MP4, WebP, or AVIF
1-bit transparency limits edge blending on non-uniform backgrounds
