I agree this HES course's, umm, focus, is about camera engineering rather than how to use the camera.
They could have mentioned how to use nice glass for composition. For example, mobile phone cameras are great. The best reason these days to schlep a CAMERA camera instead of a phone is the lens. Do you want a big aperture (narrow depth of field)? Bring your CAMERA. Do you want a super long lens for making pictures of faraway stuff. Bring your CAMERA.
Some CAMERAs have another cool hack. You can put them in to black-and-white mode and their viewfinders show black and white. That's a great way for an amateur photog to learn to see light unconfused by color.
