Sontag goes on to perform a very deep psychological analysis of personal photography, "Travel becomes a strategy for accumulating photographs." "Photography has become one of the principal devices for experiencing something, for giving an appearance of participation.", I certainly relate to this every time I take a selfie or a picture, its proof that I was there, its sort of narcissistic and nonsensical, my own memories should be sufficient, but I do enjoy looking back at them after a few years so it isn't fruitless.
Being recorded by someone else implies importance, and although I don't know what it was for, I did feel a slight importance and permanence every time we were being filmed. That moment would be recorded for some mundane purpose ~forever, and that does have psychological implications, it changes your thought process to a number of things, some maybe even self critical. Overall I found this essay very interesting, it goes deep into a subject that I would never have thought even deserved entertainment.
