Punctum in terms of mythologies

I am curious about how studium and punctum are related to mythologies, and whether or not they can each be used to manipulate an audience to think a certain way. It seems to me that any photograph will inevitably produce some sort of mythology, because its image has been taken out of context. I am confused as to the way in which a photographer can avoid the framing of a photograph.

Also, the punctum is meant to evoke a feeling of sensitivity or humanity in the observer. It goes beyond the symbolic, and resonates within an audience. Isn't this punctum necessary to successfuly sway an observer to believe a mythology? I understand that 'staged punctums' are not real punctums, simply because they are not natural. But can a someone use a punctum, taken out of context, to manipulate an audience?
