Callum Innes’ practice takes the form of an intense exploration of the possibilities of paint on canvas. He works in a number of different ways, all of which are gradually evolving in a subtle but constant progression with each new painting. Innes has probably become best known for his Exposed Paintings series – made by layering pigments onto the canvas and then removing the oil paint with washes of turpentine. Exposed Painting Quinacridone Gold perfectly exemplifies the inherent process of painting and un-painting behind Innes’ work, where the play between additive and subtractive processes means that the potential for uncertainty is ever present within a rigorous visual language.
