But we each have our own way of doing things. I personally think that P&S cameras do a mediocre job of photographing subjects that need careful scrutinization of compositional elements. The M camera is this way because of the optical viewfinder. Which is why they made the Visoflex. This must be a case where you actually try to make the image in the darkroom. That is, crop crop crop until there is a photograph that looks good. Since you are not looking at the ground glass, you don't know what is behind the subject, what the out of focus area looks like, the compositional placement of subjects and non-subjects, etc... those things that a 2D ground glass is so good at revealing. Over the past 50 years, I've shot a kazillion close-ups with 35mm, 6x6, 4x5 & 8x10. Once you find something that you want to photograph close-up and set-up your camera and frame the subject, then begins the long process of finding just the exact position so that the background does not detract from the subject, move a smidgen this way, a smidgen that way, a smidgen closer, a smidgen farther back, then finding the exact focus plane, stop down slowly and watch the DOF so that just what you want in focus is in focus... etc... sometimes for fifteen minutes for one photograph. But when you are finished, you have an image that is exactly what you want and will print without cropping and other gymnastics. And it won't end up in the circular file.
