Isn't it about the ability/skill/talent of connecting 'through' the camera probably unconsciously in a lot of cases.
I played trumpet and it often amazed me how music came through a piece of bent brass with three valves to press - I blew in one end and out the other came music of a sort. That music contained all my experiences, my practise (the scales, the chords and the listening) - not only the sum total of my musical education but also my 'self'.
It's the same with any intermediary tool that's used for creative expression isn't it?
