I have been trying to find the right phrase to distinguish the difference between the two, and I read the interview with Ralph Gibson on the thread and he said : <p> I have spent forty years working with the Leica rangefinder. The rangefinder enables one to see whats outside of the frame as well as whats inside of the frame. You make a decision predicated on the presence and/or the absence of various aspects of the subject. With a reflex, the camera determines what is seen, and half the time it's out of focus. One could follow a reflex around the world and focus it from time to time until it came across a picture. With a rangefinder you see something, you make the exposure and you continue to look at what youre seeing. The rangefinder is ideally matched to the perceptive act, the personal act of perception. I only use a reflex for extreme close-ups. <p> I like the words perceptive act <p> What is your thoughts on this ?
