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

TIFF

TIFF Strengths

Unparalleled flexibility: supports almost any color space (RGB, CMYK, Lab), bit depth, and metadata standard
Lossless compression algorithms (LZW, ZIP) guarantee zero degradation of image quality
Supports advanced features like multiple layers, multi-page documents, and alpha channels

Limitations

File sizes can be massive, especially for uncompressed or multi-layered 16-bit files
Poor native web browser support, rendering it useless for standard front-end web development
The format's immense flexibility means some software cannot fully parse complex or proprietary TIFF extensions
