To try to convey emotions by sharing pictures is utopia and act of pride. The visitor, if feels something, he feels it on his own, unless the represented situation is so involving that he can't help but identify himself behind the camera, very rare thing. As a rule, the two, author and visitor, look at the same subject through different glasses.
So, I take pictures only if there are conditions for coming off well. Hardly ever, instead, for remembering or for sharing a moment, which was only mine. After all, if it was good, then seeing images puts nostalgia, and, if it was not good, it's better not to remember.
