The mental processes that al-low an artist to transform visual images-e.g. those of his model-into a picture on the canvas are not easily studied. The authors re-port work measuring the eye and hand movements of a single artist, chosen for his detailed and realis-tic portraits produced from life. His eye fixations when painting or drawing were of twice the duration of those when he was not painting and also quite different from those of novice artists. His eye-hand co-ordination pattern also showed dif-ferences from that of novices, be-ing more temporally consistent. This preliminary work suggests that detailed and quantitative analy-sis of a working artist is feasible and will illuminate the process of artistic creation.
