Sirrandalot is not the first person to use a film-grain/film-like shader effect to give a certain feel. He is, however, the first to use Blender’s Cycles path-tracing engine to create a highly detailed physical modeling of a 3D camera body, simulate the various properties of a glass lens (then multiple lens system), the properties of chemical film, and then render scenes through this highly complex setup to generate real film-like images. Check out the final not-photos here or on Imgur.

You can download the camera and play with it yourself.
