'Whippman's landscapes possess a silent, twilight atmosphere; the images are drained of substance, their mirage-like presence apparently occurring as a figment of the fading light. They are quite unlike the reality of any SA scenery. Abstract in conception and yet not abstract in effect, they are the product of a particular  and personal artistic procedure: Whippman seldom set out to make a picture of a specific scene or object. In this sense he was a pure painter.  He composed directly on the canvas, juxtaposing planes of colour and creating new relationships between them. When he had achieved an abstract composition which satisfied him, he then subtly accented the elements which suggested a scene, remembered or imagined, and in this way conjured up the elusive and illusionary landscape images.' - Esmé Berman
