Photograph of a wooden gate marked by a blue arrow aligned against an open sky. The image functions as a comparative device: an informal cyanometer in which pigment and atmosphere are read against one another. Historically, cyanometers measured the sky by matching it to manufactured color standards; here, the arrow performs a parallel operation, translating atmospheric color into a directive mark. The alignment suggests how orientation, value, and movement are stabilized through approximation rather than exact measurement.
