这个视频演示了如何一口气一步一步实现一个完整的，令人满意的肖像绘画作品。作者直接用画笔在画布上绘制，展示和描述了创作的步骤，表现阴影，半色调和灯光…实现“马赛克色调”…重申和精炼……“细化”肖像的细节。

This video demonstrates step-by-step the procedure for achieving a thorough, satisfying portrait likeness in a single sitting. Beginning with a simple drawing made directly on the canvas with the brush, the artist shows and describes the creative steps: stating the shadows, the halftones and the lights... achieving the "mosaic of tones"... restating and refining... "particularizing" the portrait with detail.
