The film in math today was describing the value of invention in a new idea. It introduced us to new and important names that made a huge impact on the views and ideas of film. They were the first people to branch out far enough in their imagination to invent new ideas that captivated the audience of their films. Ideas like using focus made a big difference in the audiences mind set in the film and focused on the important things in the film that the directors wanted you to pay attention to the small actions taking place. Qualities like dark and bright light was found to be very useful in film as well. You could make a shot as light and free or as heavy and dark as you wanted. The use of light was useful in impacting the audiences feelings and attitude to a section in the film. Many techniques like this were introduced in the early 1900s and have changed film forever.
