Just as story evolved to incorporate film, film itself is evolving constantly. As new technological advancements in film are achieved it gives the film maker more room to work with and more possible ways to tell the story. Before synchronous sound there was the silent age of film characterized by slapstick acting being used a tool to convey the characters' emotions and the idea of the story, but with the incorporation of synchronous sound into film the film maker was than able to use dialogue, and sound to convey a message, idea, concept, or the feelings of a character. Color too which is often taken for granted was not always an available asset to the film maker. The Wizard of Oz does a great job illustrating the effect of color on the plot of a film. While in Kansas Dorothy's world is conveyed in black and white. However, the land of Oz is displayed to us in color giving dynamic to the film that otherwise wouldn't be there if the film were done in entirely black and white or color.
Advances in equipment such as portable devices and camera rigs gave film a completely different feel than what audiences were accustomed to by shooting of film on big Hollywood sets. On sight shooting a different shots while seemingly replicable give film a different feel when authentic.
Digital film and DSLR combined with the ability to use CGI that they come with have most recently effected the ways in which films are made. In the era of the photochemical chemical film process the film maker could only really do well on camera what could actually be done in real life. For instance, a sequence in which Spider-Man may be seen swinging by web from street light to street light in New York City could not have been done in the same capacity in 1950 as it was in the most recent 2012 Spider-Man film, The Amazing Spider-Man. The effect of digital film on the film industry is further examined in Side by Side.
Moreover, while the way in which film can be made continues to change the quality of the story remains relatively the same. For example, Casablanca and Django Unchained are two completely different movies separated by decades both are still quality films and one can't seriously argue that Django Unchained is a better film simply because it is newer.
