I am working my way through the Ansel Adams trilogy. In his first book on the Camera he clearly states that though people classify him as a realistic photographer, he clearly is not.
Ansel's approach to the scene is not to capture it as is, but rather to portray it as he envisions it in his mind. He discusses how he uses his camera, filters, depth of field, light, shutter speed and the multiple adjustment of his view camera to to produce an image on the film, that he will chemically manipulate through his knowledge of developer properties, then visually manipulate through his mastery of the printing process.
Basically, this years of dark room experience allowed him to know, before he pushed the shutter button, what needed to be done in the taking, developing, and printing processing, to get the image he visioned in his mind.
Digital folks have it easier because they get real time feedback of their ideas but they are doing the same thing. They are trying to capture the scene as their mind sees it. Painters do this all the time. Digital does not make you lazy, digital allow you to experiment with ideas you could not afford to wasted a shot of film on. So yes, you can see what if it is possible to get a better angle if your buddy hold you upside down by your ankles.
Adams makes it clear that he teaches his methods, not so you can duplicate his work but so you can use his technique to create your own interpretation of the scene.
