Shot at f/16 with a wide-angle lens: the bright sun peeking out exactly at the tip of the upturned corner of a traditional Korean hanok tiled roof, the small sun turned into a crisp sharp sunstar with long thin radiating spikes, a clear deep blue sky behind, the curved eave edge and roof tiles in sharp focus, everything from the near wooden pillar to the far mountains sharp. Strong contrast, crisp midday clarity. Korean architecture, not Japanese or Chinese. No text, no letters.
