The original photograph was taken overlooking Constantine Bay and Trevose Head on the north Cornish coast with a wheat field in the foreground. I never take photographs so distinctly sliced into horizontal thirds. It looks odd. Not so odd before I cropped it to a square format, but odd all the same. But then I looked at it again and thought of the Mark Rothko paintings. I have a postcard sized print which is Royal Red and Blue. So why not a blue and yellow?
