Then why bother? It's not an idea, it's a documented phenomenon in photography. I get that you've never encountered this problem and therefore doubt its existence; my response is you probably need to get out from behind your computer and out into the biomass and see for yourself. And I repeat: being at an event and WATCHING A VIDEO of an event are not the same thing. And it is important to note that if all of your attention is on a 4 inch LCD screen on which you are trying to capture an event, then you are experiencing the event as a photographer, not as a witness. A larger portion of your attention is on the operation of your recording device than it is on the event that is actually being recorded. And as I said then, no it isn't, not until/unless it can be physically hard-wired into the human brain and its input processed directly by the brain itself. Until then it is merely another object that humans perceive, in which case, if all of your attention is on the operation of a recording device, then your memory of the event is partially limited to that which is captured in the recording device. The specific reason you doubt this is that you've been sitting behind your computer too long and haven't actually gone anywhere or seen anything yourself. Get out into some biomass, go to a concert, watch some sketch comedy at Second City or something, then come back and proselytize some more.
