Photographers and developers struggle to understand and correctly interpret EXIF color space metadata in images

Photographers, image processing developers, and software engineers frequently encounter confusion around YCbCr subsampling EXIF tags when working with image files, leading to incorrect color space handling, image quality degradation, and compatibility issues across different platforms. Current documentation is fragmented across multiple sources, and the technical format is poorly explained, forcing professionals to spend hours debugging color-related issues or producing incorrect output.
