To artist Barry Dale, a work of art is something made by humans that evoke an emotional response in other humans. He is interested in the extent to which natural forms can evoke such responses.
When searching for an image, He values simplicity above everything. After that, He is drawn to indications of tension, imbalance, movement, dynamic equilibrium.
The best of his images are, to him, suggestive of relationships. These need to be strong, but asymmetrical in some way, not easily resolved. This may imply tension or movement. There may be parallel to themes in other, non-visual, art-forms, such as music, poetry, literature, or ballet.
