In photography, the person behind the camera should see the world beyond the add mode. That is to say, he or she should see things not in number but in their relationship. When seeing the elements in a scene as a mere number, you can either add them up or do some away. More often than not, final images so achieved lack punch. But when looking at them by finding out their relationships, you will start to consciously work out the viewing angles and exposure combos befitting the theme which you find it such relationships. This practice will give you more possibilities for the creative final images.
For sure, the photographer is not obliged to tell any specific or meaning story in the final images. One may choose to educate with a photo but we can also simply leave the interpretations to the viewers, which is probably more advisable for any work of art. That said, it is the photographer's burden to think up a title suitable for the picture to represent the theme in mind at the time of shooting.
