How much of the “look” is just you?

Roger and James,

Question: In your experience, how much of the “Hollywood look” of many of your movies is lighting vs. camera vs. post-production, vs. just your own skill/experience?

Take, for example Sicario or No Country for Old Men. Do you think you could get the exact same look for all the daytime interior shots if limited to only using some Aputure LED lights, a DSLR camera, and basic color grading? If not, how close do you think you could get?

Reason for asking: I’m earlier in my cinematography journey and want to have the right mindset when comparing my attempts to implement techniques of yours that inspire me. I don’t want to ever make excuses (if only I had an Arri or the right lights), but on the other hand, I don’t want to call good, honest attempts a failure because I can’t get the same quality out of my LED light that one does out of, say, and HMI or Tungsten lamp. I see youtube videos of “Roger Deakin’s favorite setup” all the time where they proceed to make something that looks not even close to the reference shot.

Would love your thoughts. Thanks and Merry Christmas and Happy New Years to you both!
