Focal travelling through the 3-dimensional structure of Kodacolor lenticular film. In the beginning the linear lenticular structure is visible and towards the end the emulsion layer comes into focus and the granular structure defined by the density of the silver is visible. In this shot the lenticules were showing towards the light source and the emulsion towards the camera. This enables an undistorted recording of the emulsion layer.

Focal travelling through the 3-dimensional structure of Kodacolor lenticular film. In the beginning the linear lenticular structure is visible and towards the end the emulsion layer comes into focus. In this shot the lenticules were allocated towards the lens of the microscope and the light source at the side of the emulsion similar to the configuration in projection. As a consequence the graininess of the emulsion is not visible as with the film flipped to the other side. The structure is optically distorted perpendicular to the linear structure of the lenticules.
