谈绘画中的错觉

人们在描绘对象时往往会产生各种各样的错觉,有些错觉会破坏造型上的准确度,而有些错觉却能有力的强化艺术形象,体现出艺术上的准确度,并能使画面趣味横生。过于准确、刻板、理性的造型,反而使画面索然无味,并将富于感情的错觉扼杀于摇篮里,从而降低了绘画作品的格调。     

中国画论视野中的画"趣"论

"趣"是中国绘画理论批评视野中的重要审美范畴,中国画论视野中的画"趣"论,大致经历了三个阶段:作为一个绘画审美批评概念,它在魏晋南北朝被引入画学批评中;唐宋时期,它得到进一步的充实和发展,逐渐升格为一个绘画审美批评范畴;明清时期,论家对"趣"作为绘画艺术的本质、特征及其来源、生成等予以了进一步的深化论述,"尚趣"呈现出前所未有的兴盛局面,体现为一种时代艺术精神和一股艺术审美思潮相别于前朝。

Monitoring detaching murals in the convent of Müstair (Switzerland) by mirror micrometry

In a parallel study, it has been shown by comparison of successive TV-holography campaigns that murals in the convent of Müstair (Switzerland) have progressively detached from their substrate over a time interval of 5 years (J Cult Herit 2009). Here, we focus on the dynamics of the ongoing detachment processes. In order to regularly measure small surface displacements in situ over a long duration of several years, a new method that we call Mirror Micrometry (MM) has been designed and implemented. This method monitors the reflection of a light beam by a mirror that is mounted to the surface of interest for the duration of the experiment. The mirror is designed to rotate about a pivot as small displacements in the detaching surface occur, thus deflecting the reflected light beam. Measurements over more than three years in the Convent Church and in the Holy Cross Chapel reveal various types of surface displacement perpendicular to the wall surface. These are correlated with relative humidity (RH) changes in the room climate. Reversible short-term variations of approximately ±5–10 μm occur with periods of one to several weeks and relate primarily to weather changes. Reversible long-term variations of ±5–10 μm correspond to averaged seasonal humidity changes. Irregular and irreversible movements in increments of 20–30 μm record very localised progressive detachment steps. A semi-quantitative correlation of approximately 1 μm surface displacement per 1% RH change is calculated. Based on the fact that nearby measuring points can simultaneously move in opposite directions, a geometric model is drawn to explain deformation by hygric swelling and shrinking of different shapes of detached layers.
