Renaissance artists used various techniques to engage viewers, many incorporating new scientific knowledge on lighting, spatial layout and perspectives. To isolate and pinpoint factors that contribute to the "magic" of Rembrandt's portraits, DiPaola used computer-rendering programs to recreate four of the artist's most famous portraits from photographs of himself and other models. Replicating Rembrandt's techniques, he placed a sharper focus on specific areas of the model's face, such as the eyes.UBC researcher decodes Rembrandt's "magic" [UBC]
Working with a team from the Vision Lab in UBC's Dept. of Psychology, DiPaola then tracked the viewers' eye movements while they examined the original photographs and the Rembrandt-like portraits.
"When viewing the Rembrandt-like portraits, viewers fixated on the detailed eye faster and stayed there for longer periods of time, resulting in calmer eye movements," says DiPaola, who is also an associate professor at Simon Fraser University and adjunct faculty at UBC's Media and Graphics Interdisciplinary Centre. "The transition from sharp to blurry edges, known as 'lost and found edges,' also directed the viewers eyes around the portrait in a sort of narrative."
..."Through these techniques, Rembrandt is essentially playing tour guide to his viewers hundreds of years after his death, creating a unique narrative by guiding the viewers' eye," says DiPaola. "This may explain why people appreciate portraiture as an art form.
