According to my interpretation of thought-above, the works can not be blamed as long as they are in good ethics. Because the photo created is a freedom of work of a person and his good value may have a different understanding by the crowd. A strong understanding of what the photographer is actually saying.
But the people who saw the photos also could not be copied from him because he had read about other photographs, because he understood someone different too.
Because there is a phrase that says "A picture is worth a thousand words" which means images that have meaning thousands of. So in conclusion, communicating is not only done directly, directly, and not only verbally, but can be through media such as photographs or images. The messages are not too complicated or long, the messages in the photo more sharp but clear about what messages are contained in the photo.
