I don't tend to think of painting in technical terms though all good practice involves developing a sound working knowledge of materials. The same can be said for technique. If style or facility replace the importance of looking, 'knowing' and then working out a visual response to a subject or idea then a painting will be correspondingly diminished. However, as in this instance and some of my drawings, I can set deliberate boundaries. In this painting of a water's edge at the end of winter/beginning of spring I limited my palette to four colours and white. This happened after reading about, and admiring the work of the artist–George Rowlett. Setting such boundaries can make work harder and set you thinking more stringently.
