**课程名称:** 老油画大师技法—灰调渲染(Grisaille) **课程概述:** 本课程将带您深入探索老油画大师们所使用的经典绘画技法。您将初步学习如何将图像绘制在画布板上,并通过调配法国群青(French Ultramarine)与焙烧土(Burnt Sienna)来混合出纯粹的黑色油画颜料。课程的核心在于掌握如何运用黑、白、灰这“三原色”来创作出富有层次感的平滑灰调绘画。 在完成具有扎实明暗过渡的灰调底稿并等待其完全干燥后,您将进一步学习油画的“渲染(Glazing)”技法。这是一种通过混合亚麻籽油(linseed oil)与颜料来创造透明色彩的技巧。您会将这些透明色彩层层叠加在干燥的灰调底稿之上,从而赋予画面深度和色彩的独特性。 课程还将为您介绍一系列经典的油画色彩,包括但不限于:焙烧褐(Burnt Umber)、焙烧土(Burnt Sienna)、法国群青(French Ultramarine)、钴蓝(Cerulean Blue)、柠檬黄(Lemon Yellow)、镉黄(Cadmium Yellow)、黄赭石(Yellow Ochre)、镉红(Cadmium red)、玫瑰红(Rose)、品红(Magenta)、深红(Alizarin Crimson)、酞菁紫(Dioxazine Purple)以及酞菁绿(Pthalo Green)。 通过这种“灰调渲染(Grisaille)”技法,您能在透明的色彩层下隐约看到底层的黑白灰绘画,创造出普通油画难以企及的独特色彩效果。灰调渲染(Grisaille)是一种先用灰、黑、白三色打底,通过阴影和高光来塑造形体的绘画方法。而渲染(Glazing)则是油画中一种将颜料与亚麻籽油等媒介剂调和,形成透明色彩并覆盖在干燥底稿上,使底稿的形体透过色层得以显现的技法。这种技法能够创造出普通油画色彩无法比拟的奇妙色彩效果。
Students will sketch an image on a canvas board. Students will mix black oil paint using French Ultramarine and Burnt Sienna. Students will create a painting using blacks, whites and grays. Students will create a smooth value painting. Students will wait for the black and white underpainting to dry. Students will then use linseed oil and colors to create a transparent glaze over the black and white painting. They will create a full color oil painting. Students will be introduced to Oil painting colors like Burnt Umber, Burnt Sienna, French Ultramarine, Cerulean Blue, Lemon Yellow, Cadmium Yellow, Yellow Ochre, Cadmium red, Rose, Magenta, Alizarin Crimson, Dioxazine Purple, and Pthalo Green. When using the colors, the student will see through transparent layers to see the black and white value painting underneath. This is a painting technique that was used by the Old Masters, called Grisaille. Grisaille painting is when an artist uses gray, black, and white to create the first layer of the painting, or the underpainting. The artist develops the image by adding shadows and highlights. Glazing is a technique in oil painting where an artist uses a glaze- like linseed oil, and mixes it with paint to make a transparent color or glaze. That is then painted on top of the dry underpainting, When the painting dries, you can see through the glaze to the painting underneath. This creates unusual colors that cannot be created with regular colors of oil paint.
