On photo.stackexchange.com, someone asked about the popular concept of the “exposure triangle” (balancing ISO, aperture, and shutter speed to make a photograph), which makes very little logical sense outside of the fact that we’re talking about three things. User mattdm posted the most epic response. It goes places, including the exposure balance scale, exposure cuboid, and exposure, uh, tricycle?
