From time to time I have encountered people mentioning "traditional photography rules" without elaborating on what these "rules" might be. Indeed, people often claim to break these rules, or sometimes even boast not to know them. But nobody ever seems to say what they are. Is there such a thing? If so, what are these "traditional photography rules"?
I am aware of guidelines, such as the "rule of thirds" in composition, the "Sunny-16 rule" in exposure, or that I should use a telephoto lens to obtain flattering perspective in portraiture. I am assuming that these aforementioned "traditional photography rules" relate to something else.
This is a terminology question, not seeking photography advice. I am looking for the definition of the phrase "traditional photography rules". The phrase makes no sense to me, yet it is thrown around as if it means something. What does it mean?
To avoid repetition of previous discussion, I would appreciate if answers specifically address "traditional photography rules". Please avoid philosophical argument about what "rules" are and whether there are any rules beyond personal ones.
