Four hundred crescent dunes march across a desert floor in even ranks to the horizon, each one a sharp sickle ridge with its horns pointing downwind and a pocket of shade in its lee. They fill the lower two thirds. Every crest line razor-sharp, the sky above plain. One figure alone in ochre walks a crest, tiny. Hard raking sun from the right. crystal-clear air, no haze, hard high sun, very high contrast with deep black shadow present, no grain. full rich colour across the whole frame with every surface carrying its own real hue, but nothing pushed to maximum intensity and nothing neon or electric, colour deep and true rather than bright, highlights clean and small with no blown-out white areas, deep shadow present
