‘Paint’ as seen when the membrane is opened and out-stretched. Dimensional values don’t disappear they just take a different spatial form on the two dimensional picture plane.
1: This flattened view of ‘paint’ shows the direction that the paint flowed to define the height. The middle being what was the top of the membrane.
2: How wide the membrane is apart at the top and bottom at the time the paint was poured defines its width and sets the boundaries for the paint flow.
3: A sense of time is illustrated by the movement of paint. This is controlled by the viscosity of the paint, ie, its depth.
Side view of the picture plane: Once stretched and mounted to a frame, the dimensional values created in the process are replaced with new values on the two dimensional picture plane (compression of depth).
