Occasionally one produces something that bears no relation to one’s intentions. A few weeks ago I decided to use chalks on blue paper for two poses of our faithful model, Kathryn. What I’d hoped to do was obtain a few delicate flesh tones. What actually happened was the brightly coloured chalks produced an effect like a small boy’s vision of a naked lady before the age of the internet. It was strangely successful, without having any pretensions to art, although I have a curious feeling that Prince Andrew might refer to it as “a harmless bit of fun”.
