I dont think you can just disregard a persons opinion simply because they say it looks cool. Maybe that is all the image does for them. Maybe it doesnt force them to think past the point of it looking interesting, different, or cool.
Let's say your spouse cooks a meal and asks what you think of it - and you say, 'interesting.' Well that clearly is a non-response.
Saying something is 'cool' is equivalent. I have no idea what the commenter means and thus the comment means nothing. Why is it cool? What about it is implying coolness? What the hell is 'ccol.'
I understand 'composition', 'color', 'DOF', 'sharpness', 'focus' but 'cool' I don't understand.
And yes, I
can just disregard a person's opinion for saying 'cool'; in fact, saying 'cool' is a surefire way to make me think "man, is this the highest level of cognition that this person has available? We swim in a sea of words about photography and, when faced with a picture that I think enough of to put out there for people's opinion, all he or she can muster is 'cool.'
Well, that's not good enough. If the picture is my best effort, I want theirs. Think of some words. Slide them into a sentence. And give that back."
If you want my best effort when I look at your picture, I expect yours when you critique mine.
'Cool' works for Autumn days. 'Cool' works for Steve McQueen or Jamie Fox. 'Cool' even works for my ex-wife's demeanor. But for my pictures, it better be at least an intelligible sentence - or don't bother.
