Remember its not always the OP sometimes is the comenters too can cause a fight - often though just missuse of words or a slightly overzealous focusing on the negtive and often a very impartial voice can see very harsh or overbearing when in written words alone.
True. I think that the type of comment that I'm sure you're thinking of are better left unposted though.
If all you have to say is "it sucks", I would rather not even see it. On the other hand - "I don't really like it... It's too soft, try stopping down a little next time" actually is helpful. ...Even without the part about stopping down.
If you don't like it - say
why. You may not know how to make it better, but if you say exactly what it is that you don't like, the person that took the picture at least has an idea of what they did wrong.
That being said - just because one person doesn't like it doesn't mean you did
anything wrong. Maybe that person just isn't in the right mood, or it isn't their style.
If
nobody likes it, you may want to find out why.
I think most of us are of the school that "if you have nothing nice to say, don't say anything". That helps avoid confrontation, but it doesn't help the photographer improve.
When I come across a picture I don't like, I usually don't comment on it. If I think I know a way to make it better, I do comment though.
I think it's a fine line you have to walk. Do you tell them that you don't like it, and maybe offer tips for improvement - or do you just move on to the next thread...? For me, I just move on unless I think I can offer help.
Which is better?
Would you rather know that there were a few people that didn't like it (and hopefully get a few tips), or only see the positive feedback?
If you really feel that it's good work, it can be hard to find out that other people think differently. I think it helps you grow though.
Just an idea -What if...
If you view a picture, you MUST comment on it, no matter what you have to say...? Try to offer tips, or at least say why you did or didn't like it.
I think that would help a lot, but some people will get hurt feelings over it.
