The image depicts an expansive sky dominated by a large formation of cumulus clouds, observed from the city of Orsay, France. The lower two-thirds of the frame are filled with dense, towering clouds, exhibiting a range of tones from brilliant white at their illuminated tops and edges to dark grey and shadowed blue-grey in their deeper and lower sections. The cloud structures appear volumetric and dynamic. The upper third of the frame shows a lighter, somewhat hazy blue-grey sky with faint, indistinct stratiform clouds or high-level atmospheric haze. No terrestrial features, human subjects, or man-made objects are visible within the frame.
