That is a slippery slope, one I've been on for a long time, and it is not necessarily productive. I have set standards so high and so stringent for myself it is sometimes a challenge just to stay excited about an image. There is always something just a little better in my mind's eye, but it simply doesn't exist, or is not possible. This can lead to boredom, disappointment, and very low output (which by the way does not necessarily mean the output is any better - that is a false equivalency).
But now I don't even know what the topic is anymore. My original point was that to one person Stephen Shore's pictures can be as good as anything by Cartier Bresson, Edward Weston or anybody else. To somebody else they suck. (I'm using Shore as one example here). That type of photography is about place and time. No obvious center of interest is necessary. Someone looking for some type of emotional focal point and purpose in a photograph probably won't find anything meaningful in Shore's work. That is fine. Then there are people like me who find endless enjoyment in looking at Shore's pictures, and are mostly bored by portraits, alternative processes, selective focus etc. That is also fine.
