Oil paint
Oil paint historically has been the ideal media for depicting the figure. By blending and layering paint, the surface can become more like skin. "Its slow drying time and various degrees of viscosity enable the artist to achieve rich and subtle blends of color and texture, which can suggest transformations from one human substance to another." Although working from live models is preferred, the length of time needed to complete a painting has led most modern painters to use photographs as references at least part of the time if not for the entire work.
