Having barely slept a wink until I was Forty . . . ( joke . . . but not half as much of one as you might think ! ) I am also and have always been deeply affected by the world at night . I have spent an unusually large proportion of my life out in the world at night . . . and have always since my early teens relished travelling on foot at night when the moon allows . . . a good moon can cast the world in a wonderful vivid half light that reduces the landscape to a limited palette of blacks , sepias , violets , blues and greys . . . and any sense of detail whether ‘ soft ’ or ‘ sharp ’ is rendered for the most part ‘ unseen ’ .
