Bioart is an art practice where artists work with biology, live tissues, bacteria, living organisms, and life processes. Using scientific processes and practices such as biology and life science practices, microscopy , and biotechnology (including technologies such as genetic engineering , tissue culture , and cloning ) the artworks are ...
Biological illustration has traditionally employed the techniques of using carbon dust, color pencil, stipple pen and ink, lithography, watercolor and gouache; however, digital illustration has recently become more important in the field. Every professional scientific illustration begins with multiple rough sketches.
Oil painting is a painting method involving the procedure of painting with pigments combined with a drying oil as the binder. It has been the most common technique for artistic painting on canvas, wood panel or copper for several centuries. The advantages of oil for painting images include "greater flexibility, richer and denser color, the use ...
In painting, it is a technique in which a paint brush that is very wet with solvent and holds a small load of paint or ink is applied to a wet or dry support such as paper or primed or raw canvas. The result is a smooth and uniform area that ideally lacks the appearance of brush strokes and is semi-transparent.
Underpaintings are often monochromatic and help to define color values for later painting. Underpainting gets its name because it is painting that is intended to be painted over (see overpainting) in a system of working in layers. There are several different types of underpainting, such as veneda, verdaccio, morellone, imprimatura and grisaille ...
In this way, the paint can be made to dry more quickly (if that is desired), or to have varying levels of gloss. Modern oils paints can, therefore, have complex chemical structures; for example, affecting resistance to UV. By hand, the process involves first mixing the paint pigment with the linseed oil to a crumbly mass on a glass or marble slab.
In painting, local color is the color of an object when seen under flat white light with no adjustment for form shadow or colors of light or secondary light sources. An example would be the assumption that an apple is "red" when it is actually dependent on the color of the light hitting it, color of objects around it, glossiness, and variations within the colors on the surface of the apple itself.

Light in painting fulfills several objectives like, both plastic and aesthetic: on the one hand, it is a fundamental factor in the technical representation of the work, since its presence determines the vision of the projected image, as it affects certain values such as color, texture and ...
