> Making a good picture involves realising how somebody looks and how they want to be seen and get them closer to that goal, it is not something where one size fits all.

Incidentally the same is true for audio: You can get what easily passes as "studio level" audio quality out of a 20$ microphone and free processing plugins these days – as long as someone or something is making the right operational choices during recording and processing.

Making good choices in absence of right answers is the hard thing about creative work.
