I know it may be considered heresy, but it is important to remember that once we define the art we want to make (the product we expect), the craft of photography becomes nothing more than a means to an end, part of an assembly line, the creation of "lucky accidents" over and over again.

Weston had a style, Adams had a style, Picasso, Rembrandt, etcetera all defined a style then worked within it.

Wedding and portrait photographers do this all the time. In a given situation they do a, b, c and d and it works every time.

Example-
a - backlight your subject against a late afternoon sky
b - have them kiss or spin or whatever or just wait for "the moment"
c - shoot 400 speed C-41 film at 400 and f4
d - send it to the lab

(this a,b,c,d process is essentially Henri Cartier-Bresson's process)

If a wedding shooter has 8 or 10 of these setups, that is all the craft they need to know to reliably produce a very artistic product. There is no need for thought about the craft or process or style or DOF or blur, camera work becomes all about the composition and posing. For most setup's you don't even need a meter.

It doesn't require sticking with or knowing "just one film", Fuji and Kodak become fully interchangeable as does color and B&W, heck consumer films like Superia and Gold will work just fine in a pinch.
