迄今为止中国美术学府中所使用的素描材料,还是铅笔、炭笔、炭精棒、橡皮等寥寥几种材料为主。这些材料的长期使用,使我们对全因素素描的方法步骤产生了片面的误解,在完成一张长期作业时,我们不得不遵循以线打稿,用排线条的方式铺调子,然后逐层深入的单一手法。这种方法使学生把大量时间和精力耗费在铺调子的过程中,容易挫伤学生敏锐的感觉,而陷入到局部观察之中。实际上古典学院式全因素素描大多是利用各种材料及多种技法完成的,传统素描的材料与技法多种多样,有一些已经在我国被广泛被采用,我不作重复的介绍了,这里主要涉及三部分内容的裱纸、作色底及绘制素描时使用的特殊材料及材料技法。一、裱纸素描纸张的准备是它完成好一张好的素描作业的基础,是在作画过程中运用各种材料、各种技法的先决条件。因此在列宾美院油画系要求课堂素描作业的纸张要裱在板子上,而且要把裱边裱在板子的侧面,利用整个板面作画。这种做法的好处是:1.裱好的画纸经过无数次上 The drawing materials used so far in the Chinese Academy of Fine Arts are pencil, charcoal, charcoal, rubber, and other materials. The long-term use of these materials has led to a one-sided misunderstanding of the methodological steps of the full-factor sketch. When we complete a long-term assignment, we have to follow the practice of writing in lines, laying out lines in a row, and then deepening Single technique. This method allows students to spend a lot of time and energy in the process of paving, which can easily dampen students’ keen feelings and fall into partial observation. In fact, the classic college-style full-factor sketches are mostly completed using various materials and techniques. The materials and techniques of traditional sketches are various and some of them have been widely adopted in China. I will not repeat them here. The three parts of the paper, color and the use of special materials and material techniques. First, the preparation of the paper for drawing paper is the basis for the completion of a good drawing job. It is a prerequisite for the use of various materials and techniques in the painting process. Therefore, in the Lebanese Academy of Fine Arts, the paper required for class sketching should be placed on the board, and the side should be placed on the side of the board and the entire board should be used for painting. The benefits of this approach are: 1. After a good number of times
