There has been a lot written (and put onto video) over the years advocating the use of a single flash and there’s nothing wrong with that. They’re often packed with wonderful advice that’s geared towards either educating those who’ve never used flash before or helping those with far too much gear to really limit themselves in order to master that most basic of techniques.
