In addition, practice shows that we often need to expose many rolls to produce one really excellent, exhibition quality image (National Geographic probably won't disagree with these statements given the level of film consumption of their photographers). Why? I use my Sony television set with a remote control that has a freeze frame button. As television slices reality into 24 images per second, an hour television offers 86.400 individual images, each individually accessible with the freeze button. Using the button however, one finds that approximately 90% of the images are useless. Eyes closed, bizarre expressions, movement blur, etc. Try it yourself once. I would guess that one has to look at 20 - 40 pictures to see one reasonable image and far more than that to find an excellent one. It's something like playing the roulette, we are in the domain of chance operations. Our Leicas expose generally in a range of 1/30 - 1/500 second, which has the same effect as freezing reality on a TV screen. The chance to produce a good picture, ideally the one that we visualized when we pressed the shutter button, should be in the order of 1 to 15 against us, depending on the subject. Remember Gary Winogrand? He understood and used chance operations. He exposed hundreds of rolls of film and stored them in a box. Years later he opened the box and considered these many forgotten pictures raw material, a source for discovering and printing fine images (in music, John Cage worked along comparable lines). It could be that the closer the shutter operates to the exact moment that we visualize the future image, the better the chances are to produce the picture we want. Maybe something like this. Immediately: 1 to 2, 20 milliseconds: 1 to 5, 100 milliseconds: 1 to10, 1 second: 1 to 100, 1 minute: 1 to 1000 and 1 week: 1 to infinity. I cannot substantiate these numbers but they are based on "best feel" resulting from many years of photographic practice. Winogrand worked with Leica M rangefinder cameras. The conclusion? Modern autofocus SLR's have a delay, between pushing the button and effective exposure, of in the order of 100 milliseconds depending on their construction. A Leica-M rangefinder camera operates with 17 milliseconds time parrallax. Once exposure and distance are set, the Leica-M is probably very superior for street/candid etc. photography as the possibility to produce the image that we visualised is far higher than with a 6 times slower SLR. Our friends in a certain photographic discussion group might have missed this aspect of Leica M photography as well.
