Why Critiquing is Subjective?

This is one of the things that I have been wanting to find an answer to since long.
Being a photographer and designer is all about subjectivity.

When we view an art / design we start with an impression of it. Over a time we start to develop an opinion about it. And these opinions over a period turn into judgments.
These judgments are what we call critiques. Thus if we analyze, any judgment is therefore ultimately what is what the judge thinks about it. And these jugdments are subjective. Thus criticism is a subjective act.
A critic is a judge of a piece of art, who gives his or her subjective judgments based on the opinions formulated after the impression of the artwork.


Any design we do, any photograph we take is all about "one's own" ideas. Thus we have the option to believe these subjective opinions for getting an idea of the showcased piece.
So from the above example and from the comments over time that I have received on it, an impression would be "beautiful shot!".
An opinion would be, "great shot!! a little dark but very nice"
A judgment (critic) would be something like "An over all brightening of the shadows would bring this boy out from the shadows, isolating him and transforming this from a cute picture to a WOW picture. He is hard to focus on because of the aforementioned darkness."

Over a long period of time a debate has been going on in my mind about, we as designers having to create for objectivity. However, I understand that, there is subjectivity all around. As discussed in one of my class, a critique is an entirely subjective opinion.
When the judgment is passed, by these critics or rather subject experts, (which again are subjective) we tend to believe them more than we would to a classmate or any other person (not a subject expert).

So ultimately we are designing for a subjective opinion, with the hope that the critic’s subjective opinion matches ours. This would lead to a larger audience believing the subjective opinions of the critics (as they are the subject exerts) and over a period of time, spanning across many people, the design becomes objective.

Similarly for a photograph. There will always be difference in an opinion if different people are to see one same photograph. No photograph will appeal to all. Or in other words, everyone WILL NOT agree on the same points.
Being a designer and a photographer enables one to take criticism positively. This is one thing I have really tried to learn.
