Art is subjective. Ten different judges will give you eleven different opinions. It doesn't mean that they don't understand it, it just means they understand it differently to you. After all what makes you or me better qualified to be a judge than the judge is? Just because you see an image one way it doesn't make that the "right" interpretation.... it's just your interpretation. I go out in the street and shoot images of miserable people holding signs. To most people they are just images of miserable people holding signs. To me they are a damning critique of our zero hours, minimum wage, consumerist society. Our camera club has a different professional photographer in each month to judge our competitions. They all like different styles and genres. We make it clear that what is important is not if they like/dislike the image but their comments on why and what they would do differently.
