Yes, rapport between the photographer and his subjects is important but I noticed that people seem to react differently when the photographer uses a different camera. I went for a ride in the car with my wife and her mother. I picked up my 35mm camera as I was going out the door. Then I got a wild hair up my ass and grabbed the Yashica-Mat. We stopped the car at a roadside ice cream stand and me my wife, her mom and Mom's dog sat at a picnic table enjoying our evening snack. I left the 35mm in the car and cranked up the Yashica. I got several really nice shots with the Yashica but I quickly finished the roll. I didn't really feel like changing the film outdoors in the sun so I put the Yashica away and grabbed the Pentax. It was the same people people in the same place, same setting, same everything except the camera. I just looked at both sets of negatives. I got four nice photos of people smiling and acting natural on the roll of 120 but I might have got one half-decent shot on the 35mm. People seemed more uptight and less relaxed when I shot them with the 35. Do you think people get some kind of "in your face" feeling when you shoot them with a 35mm SLR versus a TLR? You aren't looking directly at people when you use the TLR at waist or chest level like you are when use bring an SLR up to your face to shoot a picture. This was only the fourth roll of film I have ever shot with anything other than a traditional looking camera like an SLR or an instamatic. I'm going to have to think about this some more. It'll be a good excuse to shoot a few more rolls in the name of science. Don't you think? Regardless, this will affect how I think when I am choosing which camera to use for the day.
