There is no real need for the OP to 'disagree' with a c/c.
The OP asks for comments and gets them.
The OP should use what they want and not use what they don't.
Actively 'disagreeing' with a comment seems needlessly ungrateful to me.
I don't see how its ungrateful.
There is no rule nor social expectation that we must accept and agree with all that other people say. Indeed disagreeing is often one of THE most important things. Because its only when someone says "I don't agree with that" that the critical party is often encouraged to pose a more well rounded, more in depth reply or to cite theories or ideas that would support their argument.
If you're intent is to further other peoples understanding through critique then surely them asking questions and not agreeing is key.
Also part of developing in photography (and indeed any art) is moving from being told to doing the telling. To shift from doing what others say and having your own voice to say what you want.
Certainly, if asking a question is part of it, then further discussion helps.
A flat 'I don't agree', which I've seen many times, with nothing further is like asking for a gift and then saying you don't like it.
often times, C&C, both the asking for critique on ones photo and the giving of critique to someone elses photo, leads to a discussion. whether it is by means of agreement or disagreement, I think posting a photo for C&C is, by its very nature,
asking for a discussion on said photo. Granted, some people do not want any feedback on their posts and are upset when they get it. Others want the discussion, and are upset when they do not get it.
Part of the issue is people not being clear about what they want when they post, and part of the issue is people not being clear about what they want to offer when they respond. Whatever the case, the end result is that we have
all been guilty of giving and receiving critique poorly at some point. It is the responsibility of everyone involved to moderate their choice of words when they post.
I think one of the best ways you can give C&C , regardless of your own level of experience, is to say why you answered the way you did.
I love that photo, because....
I don't like that photo, because....
Im not saying that simply posting "great shot!" or "not feeling this one" is inherently wrong, if thats how you feel about it, and that's all you want to write...what I
am saying, is that people posting pictures for critique
want to know why you like or don't like their work. they
want the discussion, because learning what is right and wrong with a picture, and learning what people like and dislike about a photo helps us grow as a photographer.
There is also nothing wrong with the OP disagreeing with someones critique of their work.
C&C is a discussion, not a one sided argument. and in discussions, people can disagree.
However, it is just as important for the OP to remain objective about their work as it is for people
commenting. Both sides need to be open and receptive to varying opinions and suggestions.
theres no reason we cant be civil, is there?
