The Canon EDSDK documentation is a fascinating artifact of corporate-technical culture. It is not a product of laziness—the sheer volume of functions documented precludes that—but of calculated restraint . It provides enough rope for a competent developer to hang themselves and just enough structure to eventually, after weeks of trial and error, build a working application.
But the most instructive comparison is with open-source reverse-engineering projects like gphoto2 . The gphoto2 library supports many Canon cameras better than the official EDSDK in certain edge cases, precisely because its documentation is the Linux kernel’s philosophy: “Documentation is a patch away.” The gphoto2 community wiki contains detailed notes on camera quirks, timing delays, and error recovery—information that Canon deliberately withholds. canon edsdk documentation
