TEXTURE
Texture is the way something feels to the touch, or looks to the eye.
At its most basic, texture is defined as a tactile quality of an object's surface. It appeals to our sense of touch, which can evoke feelings of pleasure, discomfort, or familiarity. Artists use this knowledge to elicit emotional responses from people who view their work.
Textures are described by a whole host of adjectives. Rough and smooth are two of the most common, but they can be further defined. You might also hear words like coarse, bumpy, rugged, fluffy, lumpy, or pebbly when referring to a rough surface. For smooth surfaces, words like polished, velvety, slick, flat, and even can be used
There are 2 types of textures; real or implied
Tactile texture, or Actual texture is the way a surface would feel if you could touch it.
You may find actual texture in a sculpture or collage
3-dimensional artworks rely on texture and you cannot find a piece of sculpture or pottery that does not include it. Fundamentally, the materials used give a piece of art texture. That may be marble, bronze, clay, metal, or wood, but this sets the foundation for the work feels if it were touched.
As the artist develops a piece of work, they can add more texture through technique. One might sand, polish, or buff a surface smooth or they might give it a patina, bleach it, gouge it, or otherwise rough it up
Texture is what your eyes tell you about how things in the drawing would feel if you could touch them, called simulated or implied texture. Photography is very good at translating real texture into implied or simulated texture, but painters and draftsmen can also learn to recreate the visual appearance of textures in very convincing ways
In painting, drawing, and printmaking, an artist often implies texture through the use of brushstrokes lines as seen in crosshatching. When working with the impasto painting technique or with collage, the texture can be very real and dynamic.
Texture is something that artists can play with through the manipulation of their medium and materials. For instance, you can draw a rose on a rough textured paper and it won't have the softness of one drawn on a smooth surface. Likewise, some artists use less gesso to prime canvas because they want that texture to show through the paint they apply to it.
In fine art, the Italian word 'Impasto' (dough or paste) denotes a painting technique in which undiluted paint is applied so thickly (like toothpaste) onto the canvas or panel (often with a palette knife) that it stands out from the surface. When using this impasto technique, the artist often mixes paint on the canvas itself to achieve the required colour.
