I can pretty much guarantee his camera is working just fine...the old 'fiddle with your camera' thing is a common way to blend in.
Maybe back when Max Smart was on the TV after school it was common. "That old 'fiddle with your camera' thing" is even known to the woman sitting next to him. In fact, if there was a 5yo on the bus ...he'd say "Mommy that man is taking photos".
Everyone knows he is taking photos, they are being tolerant thats all and on the very edge of it too ...look at the guy with the briefcase. They can see he's an old man and they dont like it, you can see that too and so can Robert ...his fiddling went on way too long.
He's doing it wrong. He is not in control and yet the actions are his. These people paid to be there, they bought tickets and there is a right to privacy that they have a stronger sense of then when they are in the street. People are not the same and crammed together they will show him very quickly. RF is as unknown on the street as any of us, he is just another street photographer, a no name that once had the opportunities of another time but now he is on the same playing field as the rest of us.
So how does he compare? ...he is using the bus like a small pond to fish in the shallows. He is safe because he is elderly and the people will not harm him. The streets are dangerous for him now and he will be very selective about what (who) he photographs He relies on the people on the bus as much as he is fearful of them. He relies on someone coming to his defense as much as he risks offending someone else ...and he gets to sit down.
What did he take a photo of?, a wistful woman gazing out a window likely. Its the topic of even the most junior of street photographers ...or at least those game to take a photo on a bus. The light is changing constantly and I dont mean that as any kind of challenge, its the opportunity that the light will eventually be right for a photo. He wont get anything but he increases the potential by using film and a larger format camera. A confidence trick of nostalgia as well as the tool he is more familiar with.
Thats the amazing thing about street photography, it is supposed to be a game about the photograph and not the photographer at all, its why any street photographer can take a better photograph on that same day when RF takes his. RF's will be no better than anyone elses because he took it. We just afford him that respect. To have his lessons and all those dead voices shoved down our throats is too much when his is the weakest photo that day. Its stifling and gives us no where to find our own voices. They had their time, we are supposed to enjoy what they did...not live it over again as if we are possessed by their ghosts. Its 2015 the world hasn't ended yet. There are still things to be seen and photographed that are beyond the imagination of the past and the future of street needs to move forward so that we dont become the groundhog day some would like it to always be.
I think the distraction is to stop us from talking about the photographers here, like setting a fire at the back of the room while someone else was trying to speak.
