Aside from technical considerations, how valid is it to suggest changes to someone else's images? Isn't that just saying, "Your vision is flawed. My vision is superior?"
Isn't all we can say, "My vision matches your vision of a particular image and therefore I like it," or "My vision does not match your vision of this image and therefore I think it can be improved to more closely match what I think it should look like,"?
Even some technical issues are personal. For example, for a particular image, some people prefer a darker printing treatment, some like grain, soft contrast, filed neg carriers, blur, or even out-of-focus subjects.
(BTW, I'm not posting this as a response to anyone's criticism of my images, this post was brought about by my examination of my desire to critique others' images.)
It does make me feel good when people whose photos I like, also like mine, but it could well be that a particular image resonates in me due to my peculiar history/experiences/influences that leaves someone else unstirred. That does not make it an unsuccessful image, unless the only reason I took it was to have others like it.
Anyone have views on this topic?
