People jump on the technical because it’s relatively easy. You can study, practice, spend money on good equipment and improve your skills. It is quantifiable, repeatable and can be fairly easily graded and scored. It’s an aspect of photography that attracts analytical thinkers, engineers and scientists. People with high levels of conscientiousness and also people that tend to be, although not always, more on the conservative side. People who like order and rules. Of course you get highly creative people in this segment. Great scientific theorists, brilliant engineers and so on but it’s rare.
Really great photography also needs above average levels of creativity. A personality trait usually accompanied by a more open personality, one less bothered by rules and following what others think. A less conservative personality, more open to different points of view.
And there is the problem with photography. It requires personality traits not commonly found in the same person. Not never, but seldom.
