In my opinion:
Photography changed the way people see the world by viewing it in different perspectives. Some may see what others see, but some see what THEY can only see. Photography has helped us remember events such as the "I had a dream speech" this helped us remember what happened there. Along with the Industrial Revolution and taking pictures of workers, it tells us a story in one image; the condition they were in, their mood, and their action(s). Photography changed the way people see everything from frame to frame.
