All the Stops: An Exposure-Triangle Game

Field notes

The lesson models aperture, shutter speed, and ISO as three interactive controls, then connects the resulting scene to a scored shot and an explanation. Its progress system avoids accounts: state remains in the current browser, while a code or link can transfer it to another device. The page also notes that exposure response and depth of field rely on WebGL2, making the visual simulation part of the teaching mechanism rather than merely a presentation layer.
