I truly believe that art is supposed to wake up emotions. The most important part is that there is no stipulation upon whether such emotions positive or negative. The only requirement is that the emotional impact must be intended. Id est, an objective value of a piece of artwork (a photograph in this particular instance) is determined by a magnitude of an emotion that it creates in a viewer's brain. Quite often the emotion is not what the artist wanted it to be, because the artwork is almost never perceived identically by an audience, but if this emotion is strong enough, it most certainly will carve itself in an every recipient's memory. If, however, the emotional impact does not correspond, at least partially, to what the author has been trying to achieve, the photograph becomes worthless form an fine art standpoint.
