varjostusta

Varjostusta is a Finnish term referring to shading, the practice of applying darker tones to parts of an image to imply light, depth, and form. In Finnish art and design discourse, varjostus describes the depiction of shadows and transitions from light to dark on two-dimensional surfaces, using drawing instruments, painting techniques, or digital tools. The aim is to model how light falls on objects, giving volume and realism.

In traditional drawing, common varjostus methods include hatching (parallel lines), cross-hatching (intersecting lines), stippling (dots), and blending; control of value ranges from light to dark creates contrast and mood. In painting, glazes and layering can create soft or textured shadows. In photography and film, varjostus refers to how lighting is set up to sculpt subjects and manage exposure, using key, fill, and backlight to produce the desired shadow and mood.

In computer graphics, varjostusta denotes shading techniques where color values are determined by light interaction with material properties; these include flat shading, Gouraud shading, Phong shading, and more physically based rendering (PBR). Shading influences realism, style, and legibility in visual media.

Historically, the development of shading techniques has been central to representational art, from chiaroscuro in Renaissance painting to modern digital rendering. As a concept, varjostusta encompasses both the practical application in art practice and the theoretical study of light and value.
