I have a rather well-defined opinion about post-production, I think it’s absolutely indispensable and that makes the success of an image at least as much as the production phase (shooting).
Here are five reasons to argue my thesis:

  1. it is used to balance the limits of technology (dynamic range of sensors, optical aberrations, …);
  2. we can correct shooting errors (composition, white balance, …);
  3. we can enhance already “winning” elements of the image;
  4. allows us to make the image as similar as possible to the idea we had;
  5. it is an important creative and expressive tool.
