I've been doing a lot of photos with geometrical forms, criss-crossing lines, interlocked areas, etc etc, and I've been wondering for a while where it came from. I'm very excited by a lot of Modernist art, so it shows in photos like this:

(Yeah, it's not terrible, but it's just to illustrate the point.)
But I think I've found a more general pattern the other day: recently, I did a language lessons exchange with a student (my French for her Mandarin), and I spent quite some time trying to draw characters properly.
Lo and behold, there's a photo I took some time ago that has a very similar shape to the character for "woman" :

It wasn't a conscious decision, I just took the photo because it felt intuitively interesting, but I think it nevertheless tapped into a memory of patterns.
I've had a few other accidental inspirations, like this one:

This one, on the other hand, was the first time I was applying consciously a visual pattern on a subject:

This is another one where the pattern was applied consciously, but I was barely aware of what exactly it reminded me of when I took it:

So that's the inspiration for the how: the way I take pictures these days comes in large part from the models I have memorized.
It's imitation in the traditional sense, like Samuel Johnson writing "The Vanity of Human Wishes" on the basis of a satire by Juvénal. It's the way most people have been doing art for centuries; the fascination for the original and unheard-of (or at least the illusion we entertain about originality) is a more recent development.
As to the inspiration for the content or mood, I guess there's something similar happening: some feeling from a previous experience resurfaces before a scene, and it makes you push the buttons.
So far, that's how it works for me.
