Vignetting due to an inanimate object obstructing the FOV is not the same as light fall-off which is what illumination correction corrects although a clever PPer might crop the vignetting away or Heal it away for areas conducive to a healing action.

Yeah, I always figured the correction was likely just based on shooting parameters, but I wasn't sure if there was some image analysis part of the correction too. Thanks for the clarification.
