That explains why I've always felt the advocates of the SOOC or purist philosophies are driven more by a desire for increased discipline than increased creativity. Increased discipline can sometimes lead to increased creativity, so I'm not dismissing the importance of that. Even so, it doesn't always lead to increased creativity and sometimes increased creativity is born of a lack of discipline, such as when we make a mistake that results in greater creativity.
I don't buy the argument that using the discipline to get it right in the camera always becomes easier and quicker each time you do it. That can apply in certain situations, such as when making a "correct" exposure. However, when I work in my makeshift studio, there are many situations that aren't repeated often or quickly enough for the newly acquired skill or accomplishment of one setup to transfer to the next setup.
