Canon-CR2

Canon-CR2 Strengths

  • Retains maximum sensor data, allowing extreme recovery of highlights and shadows that would be permanently lost in a JPEG
  • White balance and color profiling are not 'baked in', meaning they can be completely altered in post-production without degrading the image
  • Lossless compression ensures perfect pixel accuracy while reducing file size compared to fully uncompressed formats
Limitations
  • Proprietary format means it requires constant updates to raw processing engines (like Adobe Camera Raw) every time Canon releases a new camera model
  • Produces very large file sizes (often 20MB to 40MB per image depending on sensor resolution)
  • Cannot be directly embedded into web pages or used in standard HTML/CSS contexts
DXF

DXF Strengths

  • Universally supported by almost every CAD program, 3D modeler, and vector graphics editor in existence
  • ASCII structure is human-readable and can be parsed or generated programmatically with relative ease
  • The de facto standard for sending 2D cutting paths to CNC routers, plasma cutters, and laser engravers
Limitations
  • ASCII DXF files can be enormously large and inefficient compared to binary DWG files
  • The format relies heavily on legacy AutoCAD data structures, making complex 3D entity parsing extremely difficult for third-party developers
  • Lacks native web browser rendering capabilities
