Crescent dunes of saturated rust-red sand march across the frame in even ranks, each sickle crest razor-sharp with a pocket of violet shade in its lee, green scrub in the troughs. They fill the lower two thirds. 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
