Nicéphore Niépce produced the first successful photograph from nature in 1826 or 1827, an approximately eight-hour exposure of the courtyard of his estate, Le Gras, made with a camera obscura and a pewter plate.

Notes on verification

Core facts (Niépce, Le Gras, pewter plate, camera obscura, 1826/1827 date) are well-corroborated by multiple independent sources including Wikipedia, conservation science sites, and history-of-photography references. The 'eight-hour exposure' detail is a traditional estimate repeated widely but disputed by some modern researchers who argue it may have taken days; claim's use of 'approximately' mitigates this.
