本文主要对于素描教学环节中,在空间的表现方法上,色调的虚实强弱对比是具有很大的作用的。但是,如何准确的控制色调的对比度是一个很难的问题。这首先,就需要摒弃经验的教条思维。其次,以知识为基点,细心、客观的进行观察。其关键的是需要将物体放置于空间之中,与其他物体和环境有效结合起来,总结其中的变化规律,抓住要点;从而准确的把画面的色调层次、强弱对比、虚实变化等素描要素能够较好的掌握,从而达到教学的目的。
This article is mainly for the sketch teaching, in terms of spatial representation, contrast of the actual strength of the color tone is of great use. However, how to accurately control the color contrast is a difficult problem. First, we need to abandon the dogmatic thinking of experience. Second, based on knowledge, careful and objective observation. The key is the need to place objects in the space, and other objects and the environment effectively combine to summarize the law of variation therein, to grasp the key points; thus accurately the picture tone level, the strength of the contrast, changes in the actual situation and other elements of the sketch To better grasp, so as to achieve the purpose of teaching.
