Advanced Sketch Drawing
Advanced Sketch Drawing
Advanced sketch drawing is still done free-hand drawing with pencil and eraser. It differs from regular sketch drawing because it involves a greater concentration and understanding of the elements of the subject.
The sketchbooks of famous artists such as Leonardo Da Vinci, Edgar Degas and Rembrandt van Rijn are now considered to be works of art in themselves.
In 1882 Vincent Van Gogh wrote: "There are two ways of thinking about painting, how not to do it and how to do it: how to do it - with much drawing and little colour; how not to do it - with much colour and little drawing."
素描石膏
以石膏像作为初始阶段的教学内容，其有利条件是：其一，石膏像是白色的物体，便于我们观察人物头部形体结构的转折关系及层次差别；其二，石膏像是静态的，对于初学素描写生的学生而言，这为他们细致、耐心地观察和描绘对象提供了最大的方便。
素描石膏是一种用线与面的表现方式来表达的.每一个物体在光照下都有亮灰暗三部分.从最深到最亮依次是:明暗交界线,暗部,反光,灰部,亮部.在作画时,亮部要尽量避免脏,暗部要尽量避免闷(即由于线条太多而没有空隙与反光)。
素描石膏是其他艺术的必然基础，尤其是水彩，油画，版画，雕刻(浮雕)，另外对平面设计，也是画草图的必要基础。素描虽然被视为是两度空间的艺术，不需要颜色及第三度空间，却也同时暗示这两者。
素描石膏的明暗五调子:明部,半明部,明暗交界面（最暗）,投影面,反光面素描石膏要注重基础画多几何体很提能力！
