Alternatives to the traditional classical recording (Part 2)
Your conclusion is pretty right on. And as a general rule of thumb, I think close mic and the tools available today give recording artists a large number of choices that can be used until experience takes over!
The microphone, like everything it is recording, is an instrument. An experienced expert with a microphone has a similar kind of control over timbre and dynamics as a cellist with a bow or the embouchure of a brass player. But it needs as much practice. And the other side of this is the wide array of signal processing that is now cheaply available to a wide range of recording artists.
Like a composer learning orchestration, a recording artist needs to start with rules of thumb and begin to experiment and explore. Recording can just as expressive as a performance, and as sampling rate and bit depth begin to give more head room in the information domain, recording artists will begin to have new dynamic and expressive room to explore. It is in the details beyond the rules of thumb that digital recording can now start to explore, but these are aspects that take much trial and error.
In other words - save, tinker and undo often!
