code behind the camera

The shot, parsed.

Every photograph is a few million numbers wearing a nice outfit. This panel undresses one: the EXIF as honest code, the dominant palette pulled straight from the pixels, and a live RGB histogram, all computed in your browser with the canvas API. No faked visuals; feel free to view source.
