Rembrandt used optical tricks to paint self- portraits

The 17th century Dutch painter Rembrandt may have painted his celebrated self-portraits with the help of optical projections created by assemblies of mirrors as per a new study. Researchers identified several arrangements of a flat and curved mirror or a flat mirror and a lens which they say can recreate the perspectives, proportions and lighting seen in the self-portraits of Rembrandt .The similarity of his images to projections in their lighting and soft focus along with the use of lens technology by his peers and fellow artists and contemporary literature on the subject all support this. The study details several combinations of subjects, mirrors and a projection surface that result in projected images that almost exactly match the physical measurements taken from a sample of Rembrandt’s self-portraits.
