Since its discovery, photography has been a constant companion of humanity. It has become a valuable document, a reliable account of the events in human life. It has its own essential role in science, advertising, photojournalism, and communication, and it is gradually establishing itself as a significant and democratic art. All genres of photography have the potential to become art when they go a little further and convey a new concept, feeling, or message, as well as the original creative views and ideas of the artist. Photography has entered museums, become part of the inventories of institutions, and there are even independent photography museums in many places around the world.
