A typical definition of the adjective “objective” is “expressing or dealing with facts or conditions as perceived without distortion by personal feelings, prejudices, or interpretations.” (Source)
TCQ is premised on the principle that photographs cannot be completely “objective.”
Anyone who disagrees with this perspective can post online an example of a photograph that they consider to be completely “objective” and to invite comments.
Even if a camera is set up to record photographs while no one is present (say, to track wildlife) there are still human decisions required with regard to which camera/lens is used, where the camera is placed, where the camera is pointed, and how wide is the view that will be recorded.
Note: Variants of the term “objective” can refer to a lens in some languages (in German, a lens is an Objektiv; in French, it’s an objectif).
