对于初学者来说,素描的“虚实”问题是至关重要的,要真正解决这个问题决非易事。总结多年的教学经验与艺术实践,“虚实”归纳起来就是:方实、圆虚;前实、后虚;近实、远虚;转折的地方实、非转折的地方虚;结构的部分实、非结构的部分虚;受光面实、背光面虚。这样虚实相间,画面才有变化。 For beginners, the sketching of the “real” issue is crucial, and it is never easy to really solve the problem. Summarizing many years of teaching experience and artistic practice, the “real and imaginary” can be summed up as follows: Fangshi, Yuanxu; Qianshi, after the virtual; near reality, Yuanxu; turning point of the real, non-turning point of the virtual; part of the real structure, Non-structural part of the virtual; light-receiving surface, the backlight is empty. This virtual reality, the picture has changed.
