Still have to know what settings to use.. AUTO doesn't cut it most of the time. If they don't know their body, they CANT get a decent shot of a kid sitting on a bed!
I disagree with your whole premise. If you don't know your camera, and appropriate settings... you can have the best light in the world, and the best eye in the world.. and you are still going to get shots that are under / over exposed, blurry, poor color and with lousy DOF choices. (wow... we see a lot of that... wonder why!)
you don't just learn one thing at a time. You are introduced to concepts that then make you think about how they interrelate with the other things you are learning.
While learning to master your body... you actually do assimilate many other concepts about light, and composition... especially on a forum like this one!
This sounds like the same argument we hear from the new "Quasi-Pro's" all the time... those that say skill with the camera isn't as necessary at being "artsy"..... I say you need it all! And not knowing your body and settings will limit you creatively, because you WON'T be able to capture you what you see in your vision, because you don't know how to setup your camera and lights to do it.
QUESTION!!! If you have a painter, who is a MASTER of light and composition... really exceptional (this IS what you are suggesting, right?)
. But this master has NEVER touched a camera in their life (just a noob in photography)! And you hand that "master" a D4, with top end lenses, and a couple of strobes.... what kind of shots are you going to get?
You will get well composed and framed, underexposed / overexposed, ... SNAPSHOTS (with blur, poor WB, and lousy DOF! ANd a very frustrated master!)! At least until the "Master of light and composition" learns the settings on that camera, and the basic concepts of photography!
