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

SVG

SVG Strengths

Provides infinite resolution scalability, looking perfectly crisp on high-DPI (Retina) displays without increasing file size
Extremely lightweight compared to raster formats for flat graphics, logos, and UI elements
Can be manipulated dynamically via the browser's CSS and JavaScript engines (DOM integration)

Limitations

Unsuitable for complex photographic images or photorealistic textures
Poses critical security vulnerabilities (XSS and XML External Entity attacks) if user-uploaded SVGs are not heavily sanitized
Rendering performance degrades significantly if the SVG contains tens of thousands of complex nodes or deeply nested paths
