| The aim of our study is to discuss Annular Solar Eclipse illusion observed in video work (Suzuki, 2013), shot in 20-21 May 2012, which is similar to New Moon Illusion (Sugano, 2007) and to investigate the factor of these illusion. As it appears in Turner's painting Fishermen at Sea, visual artists express the Moon as figure on background of altocumulus cloud as ground. Sugano (2007) pointed out there is the reversal of figure-ground in perception of moon and clouds. Suzuki's video work Annular Solar Eclipse and Clouds showed three types of optical illusions occur, when a moving altocumulus cloud forms at the same time as Eclipse starts. The first occurred when Full Eclipse started. The perception in this case was that two-dimensionality changes to three-dimensionality as the cloud passes Full Eclipse. The second illusion occurred as the altocumulus cloud was actually passing behind rather than in front of Partial Eclipse. The third illusion was that the cloud passed in front of Partial Eclipse: the perception was as if the cloud was actually wrapping around the Eclipse. Our result from observation was consistent with the findings of previous studies on the factor affecting figure-ground perception. |
