"Photography cannot depict abstract concepts. Photography cannot depict mental states. Photography can only depict whatever consequences such concepts or mental states have in the world, alluding back to what might have caused what is shown. An obvious solution is to put some text next to a photograph. If you can’t see it, literally point it out, using words. Large parts of photojournalism operate that way: Get some dramatic picture, add a possibly even more dramatic caption, and you can make sure that your viewers get what you want to tell them. Or maybe not. But either way, such an approach to photography works fairly well, especially in the context of the news. But it’s also rather limiting. What if your viewers don’t see what you want them to see? What if your viewers are tired of being hit over the head with simple messages all day long?"
