F: David MacDonald is best known for his work with water-color painting. His work has been included in over 36 exhibitions. He is also renowned as an art teacher, with work in a summer water-color painting intensive program for high school students. David, how did you start making art?
M: Initially, it was a way to create some private space. As the third in a family of nine children, I always shared a bedroom with at least three of my brothers. I would help my parents unpack the groceries, then unfold the paper bags so that I could use the inside as drawing paper. Through hours of drawing, I was able to create my own little world. I was introduced to water-color painting during my second year in college and ever since then I have been fascinated by it.
F: What is the source of your ideas?
M: Anything can become a conscious or unconscious inspiration. I can get lost in the country or in the city streets or in the supermarket, even the shapes and colors of the vegetables give me all sorts of ideas. On a more scholarly level, I was influenced by Chinese and Japanese painters during college.
F: Is there any advice you would like to give to our students?
M: An artist has to believe in him or herself. The dedication, courage and energy my students bring to the classroom are more important than anything I can offer. If you want to stand above the crowd, your passion for your art must be manifest through a willingness to work harder than anyone else. The students who succeed see their art as a way of life and not simply as a way of earning a living. My job as a teacher is to help my students realize their potential and to bring eloquence to their unique voice.
