I believe that we should take into consideration what circumstances the artist was in. I also believe that although you may not like the work of art that has been created… you should find the positive in the picture first, tell the photographer, and then nicely ask them what they did and maybe suggest doing something slew. Try also to look symbolically at the picture and not just literally. Sometimes you have to look at the photo for a while to find the symbolism. Take the time to respect the photo and the photographer.
