The missing edges of Rembrandt’s painting The Night Watch have been restored using artificial intelligence. The canvas, created in 1642, was trimmed in 1715 to fit between 2 doors at Amsterdam’s city hall.

Rembrandt actually used 4 different colors to paint a miniscule light effect in the eye of one of the many life-sized protagonists featured in this group portrait, which probably wouldn’t be seen by anybody anyway.
