The next experiment should make use of four cameras. Two identical Leicas and two identical Rolleicords. Have an assistant load one Leica and one Rollei with the same film, and the other two camera should be loaded with a roll of heat damaged or other film. A coded master file should be locked in a filing cabinet at a separate location with the key to which camera has which film.
You should have a $100 bet with two separate photographers about how good an image you are going to get. This adds incentive. You should go with you assistant and the four cameras to an ideal location and make the picture, knowing that possibly only one shot will work out. You should repeat the exercise six times.
This way you are likely (<0.05 chance of failure) to have two images from the two different cameras at the same location and time, even though you will have taken each shot as though it will be the only worthwhile picture on that occasion.
Then crop as Randy mentioned.
Huh? I followed everything I added an underline to. After that, you lost me. In part, you seem to be describing a double-blind experiment. But heat damaged film? $100 bet? And how do you know that p<.05?
