Kodak-DCR

Kodak-DCR Strengths

  • Preserves the full dynamic range and uncompressed raw sensor data captured by foundational professional digital cameras
  • Utilizes the standard TIFF container structure, ensuring that open-source decoders like LibRaw can easily parse and interpret the files long after official vendor support has ended
Limitations
  • Completely obsolete proprietary format tied to camera hardware that is no longer manufactured
  • Shares the TIFF magic header, leading to widespread misidentification by automated MIME detection libraries
  • Cannot be natively viewed in web browsers or standard operating system image viewers without specialized codecs
PICT

PICT Strengths

  • Incredibly versatile for its time, allowing a single file to cleanly scale text and vector shapes while simultaneously housing raster photos
  • Served as the flawless universal clipboard format for the classic Mac OS, enabling seamless copy/pasting between wildly different applications
Limitations
  • Deeply tied to Apple's legacy QuickDraw graphics architecture, making it exceptionally difficult to write accurate third-party parsers on modern operating systems
  • Lack of a standard magic header makes file detection unreliable without seeking 522 bytes deep into the file
  • Completely unsupported in modern web environments and discontinued by Apple itself
