The title of Land's Film in Which There Appear Edge Lettering, Sprocket Holes, Dirt Particles, Etc. (1965-66) describes exactly what we see - technical details of the film's materiality that are normally invisible to the viewer. Instead of an unfolding narrative, we see two types of test film-strips side by side, filmed in close-up. One shows edge lettering and the other, color bars, flanking one full and one cut-off image of a seated woman in a red dress, smiling into the camera - the so-called 'China Girl' featured in test leaders used by film laboratory technicians to calibrate the image when processing the film. As we watch, the woman occasionally blinks, rupturing the otherwise unchanging image. Land presents us with the equivalent of the back of a canvas, denying us the cinematic absorption we seek, and replacing it with an awareness of the process of our own looking.
