OK so Roland Barths piece is on photography which is related to cinematography and so we can try to apply these principals to our work. So when I refer to photography in this case I mean both photography and cinematography. There is an interesting point where Barth's describes two terms,
stadium and
punctum (both from Latin) to try to talk about the information in the images and the effect it has on the viewer.
Punctum is what makes a photograph interesting to the viewer, your point of understanding... Studium allows us to experience the photograph.
He mentions the camera obscura which proceeded photography. I think we had an understanding of the ideas in an image before we get to photography and even painting. But, Barth is trying to create a "clarification" of these ideas.
Surprise is expounded on and in some ways I think we part in thinking here for the high speed photo that stops time and reveals something interesting is a perfect example to me but Barth in unimpressed.
Finally he gets to the point that "Ultimately, Photography is subversive..."
Barth then goes on to talk about the importance of detail. and how this can provide the
punctum for an image.
Finally it all boils down into the "eye of the beholder."
