Oil painting
One of my favorite hobbies
Oil painting is the process of painting with pigments with a medium of
drying oil as the binder. It has been the most common technique for
artistic painting on wood panel or canvas for several centuries,
spreading from Europe to the rest of the world. The advantages of oil
for painting images include "greater flexibility, richer and denser
colour, the use of layers, and a wider range from light to dark".
