Whenever I ask someone about a feedback for any photo I take, whether it's good or not, they respond like "It depends on the story you want to tell. What story you want to tell". Now I'm sure it has some meaning. But I don't understand it for all photos.

@Vikas I don't think all photos have to tell a story, necessarily. But for simple objects, unless it's a still-life–type study, where every single bit of the composition works together to make a good picture, any sort of "mundanity" can kill it, and turn the photo is "just another flower/road/brick/etc.", right? For example, spend awhile with the photos in 500px.com's Editor's Choice feed and compare with similar photos you (me, etc.) produce. Compare similar

... themed or composed photos, and determine what generally makes theirs so good, and where one's own effort differs.

Are all of those 500px Editor's choice photos telling a story? Perhaps, but probably not. But they are compelling, and stand up to a general, "what do you think of this photo?" type question. Most of my efforts don't stand up nearly so well. But some of my favorite photos I've taken have a story (although, usually a personal memory, the story isn't conveyed in the image). But perhaps that's what separates the hobbyist from the auteur / professional... ¯\_(ツ)_/¯

But I think the reason people respond with, "it depends on the story you want to tell", is because art is highly subjective. Without any context, people are left to just judge things based on... essentially the tastes and preferences of the viewer. But if the viewer has some sort of guidance about what the artist was trying to say, that changes the interpretation of the viewer. Sometimes art is just for art's sake (ars gratia artis), but usually there's a meaning or further intent behind it.
