Do people who take photos today still use the Sunny 16 Rule? Do they even know about the Sunny 16 Rule? I think it might be regarded as a little old-fashioned now. After all, it is firmly rooted in the days of film. If it isn’t being taught (and I’ve taken a quick flick through a selection of recently published photography basics books and can’t find a reference to it) that’s a shame, because I think it’s rather useful.
