Jan Vermeer, Signora che scrive una lettera (dettaglio), 1670 ca. Dublino, National Gallery of Ireland
#ClippedOnIssuu from Drawings by Nikolay Blokhin
'Vermeer’s The Lacemaker. Fascinating close- ups'. It is generally accepted that Vermeer employed a camera obscura when working. One of the tell-tale signs of the presence of a lens is when 'discs of confusion' appear. These bright specks of light are a characteristic of all Vermeer's mature works.
