I have, apparently, been noodling on this for about a month. The problem of getting from "I wish I could make a picture of some sort" to a clear mental image of that picture is a tricky one, and I wrote out some ideas on how this process works, and what you can do to speed it along:
Photos and Stuff: Whence Inspiration?
Photos and Stuff: Inspiration Thought Experiments
I will probably rattle on for another few hundred words on the subject over the next couple of weeks, or until I see a shiny object of some sort.
I read all four of your essays today, amolitor. And I must say, I was mostly in agreement with you until I arrived at the following passage:
"You can produce pretty good portraits, and mediocre street, by conscious thought. For very good work in both areas inspiration is necessary, there's simply no time to consciously think your way through the possibilities and find a truly great image by sheer mental effort. You might find one by accident, but not through effort. "
Your use of Henri Cartier-Bresson throughout the essays as an example of the, let's call it the "instantaneous" school of previsualization falls apart, terribly, once one becomes privvy to his contact sheets. Peeling back the veneer of mastery, you will find frame after frame after frame of utter crap. Specific scenes and locations, shot after shot, muffed...the people in the FOUND SCENES being out of position,m doing boring chit, and so on. What he presented as his "decisive moments" were in most cases, the result of good timing on scenes that he "worked at capturing". The same is true of the work of many other famous street and candid shooters of the B&W film era of the 1930's,40's, and 50's; their images, the ones that they actually SHOWED, were very good images.
The idea of that the old street photography master practitioners saw scenes as "decisive moments" and made their images without much effort or thought is utter bullspit...looking at their contact sheets, it's CLEAR, blatantly clear, that they "worked" situations, hard, snapping away, failing in the majority of cases, and occasionally, things in the real world came together, and were actually interesting enough to make a print from a frame. Occasionally.

Cartier-Bresson's famous bicycle in alleyway shot from the second story....zOMG...it looks like a hobbyist's contact sheet...it's a "lucky shot"...he tried and tried and tried and tried, and finally, he was lucky enough to get something "interesting enough" to make a print out of. The rest is utter rubbish. He spent a lot of time, and "effort" to get a decent image. Same with the hundreds of other scenarios that resulted in good street images--the contact sheets prove that there was huge effort expended,most of the time. We cannot let the cream of the crop hide from us the huge amount of effort digging in the dirt to get that crop to market.
