Art is usually considered as subjective. There’s nothing further than the truth.

What is subjective, is the experience and perception of it by different people at different places and times. The truth about what a work of art is though, isn’t.

It is permanently objective.

It has nothing to do with opinion, taste or preference. It is the thing it is, regardles of how it is seen. Only the perception of the art work is subjective, the work itself, what it actually IS, is objective, separate and detached from its external perception.
