Are" techniques" measuring the light, setting the aperture/shutter speed/ISO, and focus, and pressing the shutter? The dictionary offers circular definitions that beg themselves. What are "techniques," anyhow? Is a setting on a machine a technique?
I was at a gallery and struck up a casual chat with another viewer. He was elder, say late 70s, and was wearing what I call the photographers outfit; multi-pocket photo vest, light meter (like a watch on a fob) AND a loupe (another fob), khakis and sensible shoes. We were admiring an image and he started describing the lines in the image to analyze it. I said, "I don't see any lines, I just experience balance,"; I compose from the gut. He insisted that there were lines to be seen underpinning the composition. I told him very clearly that there were no lines except those he was imagining. He needed to reduce understanding to something measurable by an abstract idea. I bet he studied "techniques".
I guess my self-teaching, the mechanics of the camera, understanding what goes in the frame and how dark or light things should be, doesn't consider technique. There is just the doing. It may be that, while I can tech-up, get all sciency, and do data analysis with the best of them, that has always been in the background. I have well-developed pathways for that sort of thing. It is even genetic if you look at my parents and grandfather. Grampa, who was a goatherd, gathered and cut driftwood on the Berkeley mud flats, selling it in the windy bayside Oceanview neighborhood in the 20s & 30s. He made chicken and rabbit hutches and sheds without a measuring tape or square. He just made them.
Back in the 90s I presided over the Photo Department's Technical Advisory Board at the invitation of a former instructor. I wondered aloud that one either was a photographer or not. I wondered about teaching people in spite of their proclivities. As I spent more time teaching than shooting, working directly with the modalities of photography and students, I saw that there were certain students who were simply naturals. After they learned the mechanical basics they just went out and shot and produced wonderful work. Vision, talent, confidence seem to blow past abstracts.
So, maybe, techniques may be less critical for some than others and ends pretty early in the productive process. Natural facilities or pure experience can appear to operate without techniques.
