Real Time

Rolling Shutter

Dr. David Monaghan and Conor Gallagher WORKING ON THE DEVELOPMENT OF THE PIECE AT CLARITY DCU, AUGUST 2012

'Real Time Rolling Shutter' is a new installation by Connolly Cleary made with the collaboration of CLARITY (Dr. David Monaghan wrote the code) as part of their 'Look Both Ways' commission for RPA.

The OBJECT IS to create a mirror-LIKE ‘rolling-shutter’ INSTALLATION where the live IMage DEVELOPs FROM BOTTOM TO TOP OVER FOUR SECONDS. TIME is expressed as a geometric distorsion and, as in a fairground hall of mirrors, the experience is as much fun as it is challenging

About a year ago Dr. Patrick Cavanagh suggested that we explore something called 'shutter-plane photography’ and try to adapt the technique to digital video for one of our ‘mirror’ installations. Our research has led us to an investigation - presented in the slideshow below - of a fascinating early photograph by Jacques Henri Lartigue, Une Delage au grand prix de l'Automobile-Club de France (1912), which presents a geometric distorsion of bodies moving through space, allowing us to see time as a dimension like any other.

THIS SUMMER, with Dr. David Monaghan of CLARITY, WE TOOK ON A PROJECT OF applying such time-based distorsion to live video. we divided the video matrix into 120 rows and applied a progressive delay of one frame per row, from bottom to top of the image. at 30 frames a second, this meant a 4 second delay from bottom to top of the image:

ON 23 August the new installation was given the pLace of honour in the atrium at the Hall of mirrors opening at lcga, limerick. like the fairground hall of mirrors the show takes its name from, the new piece is as much about having fun as it is about challenging the perceptive intellect:
