Yes, these are all techniques, AKA, approaches, to making art, including photography, but it is also is up to the photographer to decide which approaches he will take, when making a photograph.
Adams knew this, as did other good photographers, and was able, as are other photographers/snap shooters, to "pre-Visulize" the image even before breaking out the camera.
Just as some 'fail to see and hear the grasshopper at their feet, so to must the photographer, be aware of his/her surroundings, including the light and ways a photograph can be made.
You can no just learn techniques and say you know it all, you must be able to "See" and that is why I recommended "Drawing on the Right Side of the Brain".
Consider the double meaning of the title, and study with the text, on how to "See" or "Draw" upon your own mind, the art that is all around you.
After all, if you can no do that, you may well only make photographic art, that does no stir up thought or feeling, in the viewer, which you do no See for yourself.
Then there is the fact, that of all the artists of all sorts but focusing on The Graphic Arts, the vast majority, will make both bad and good art, that never incites others to admire anything but the "techniques" used.
Face it, Really Good Art, is a rare thing among the ocean of effort others make in these fields, just as people with Really Good 'Taste' are also rarely encountered in the living of most peoples lives.
You can study and try to learn different Approaches, and how to see, hope you see a blinding light of realization like in the movie "Phenomenon" , or simply learn to draw on your own natural abilities, knowing, if you already do no know how to approach a photograph, the possibility exist that you never will; so become the best technical photographer you can and let others make up their own minds what they see or do no, in your work, and be silent as to your own lack of insights.
There is more, endless discussion on these topics, but I suggest you simply work on your own 'kung fu' when it comes to your art/[photography and be happy with the things that do result that make you happy.
Everything else is just a Challenge.
Cheers
