David has exhibited internationally and has been represented by two of Canada's leading galleries in Yorkville, Toronto. At present, he represents his own work.

David has travelled extensively in nearly 50 countries. This broad range of exposure and his love of nature are evident in his paintings.

One of Canada's foremost Contemporary Realists, his work has evolved from photorealism in the early 80s to what he calls 'a tightened form of impressionism'. "Upon close inspection, his work seems to dance with the borders between realism and impressionism."

For museums and collectors interested in assembling a special collection of museum-grade landscape paintings by David Howells, special viewing arrangements can be made.
