Here are exercises in light and shadow in drawing, accompanied by an instructional video. In addition, an explanation of the problem of our perception of shades due to the influence of various factors.
light and shadow
Light and shadow in art, is a technique that involves the use of strong contrasts between light and dark, which affect a complete composition. Artists known for developing the technique include Leonardo da Vinci, Caravaggio and Rembrandt.
Creating light and shadow in drawing is used to create a three-dimensional illusion and an expression of volume and depth. How the composition is created is affected by the definition of the position of the light source in relation to the format, the definition of the light intensity and the rules of light distribution on the object and the background. It is important to know the degrees of the shadow and their location on the object, the objects next to it and the background. Proper grading of the shadows will help express volume and three-dimensionality to the whole composition.
How light and shadow are expressed in the drawing depends on the chosen drawing means. Means of drawing such as pencils, charcoal and pastels make it possible to create shade and shade ratings by the amount of pressure exerted on the means of drawing. With means of drawing such as pens and markers color ratings cannot be created, so the line and line grids are the ones that create the illusion of light and shadow - the shaded places will be created using a dense line of lines, and the bright places will be created by a very spacious grid, leaving bare pieces of white paper. In painting the light and shadow are reflected in the shades of color. There is a tendency to darken a color for shade by adding a black color, but the more successful method is to add a complementary color that provides a richer hue.
