Les Walkling, in an article titled, “Understanding Pictures - a brief summary”, talks about the five compositions: Drawing, Tonal, Colour, Spatial and Temporal. The following quotation gives a feel for his reasoning and the idea that the five compositions “… equally represent things that can’t be seen - our thoughts, beliefs, feelings, and desires.”
Pictures are composed of images, both real and imagined. Pictures are also constructed (design) as well as composed (meaning). While their meaning is largely subjective, their design can be objectively defined according to its Drawing Composition (which defines the relationships within the image), its Tonal Composition (which defines the drama in the image), and its Colour Composition (which defines the mood or personality of the image).
Many writers dwell at length on the “Drawing” component because it is so easily demonstrated by word and image, less so on the tonal and colour compositions and rarely on the spatial and temporal. Bringing all five together has the potential to create an image with depth and wholeness. Fully understanding how that can be achieved probably requires attendance at one of Les’ workshops.
