The first insight I had as to the Berger video was how perspective can change how we perceive art so drastically. Seeing art in person the way the artist intended it to be seen, with it's original texture and surrounding environment can change how we view the artists work. Texture aside and relating to the environment, whatever other senses are stimulated when viewing the art can also change how it is perceived. For example music in the background of the art piece can alter one's perception of the original work that they would not notice by viewing it outside of its original showcase.
The second thing I noted about the Berger video was his disapproval of the camera. Berger argues that the camera takes away from the original beauty and intention of the artwork in the ways that I discussed in the previous paragraph. There is unintentional distortion in the use of a camera when a photo of art is taken. Either through movement, loss of texture, or loss of background a camera is never able to capture the full intention of an original piece of art.
