This study concerns the deliberate subordination in painting of thirteen art elements and principles, the primary pictorial features, and examination of the intervals between pictorial events, the pictorial interface. A written record was kept of the artist's observations and impressions during the making of ten nonobjective paintings and their later study. The artist selected five paintings as more successfully subordinating the primary pictorial features and three paintings as most successfully exhibiting the three characteristics determined for the pictorial inter face: (1) conceptual resonance, (2) ambiguity, and (3) unbiasedness. The three paintings selected as most successfully exhibiting the characteristics of the pictorial interface coincided with three of the five paintings selected as more successfully subordinating the primary pictorial features.
