Shadowy Figures Quicktime Vr

Shadowy Figures is a 120cm x 120 cm, computed fringe digital hologram, full colour three channel white light viewable hologram of a draped figure. It embodies the visual research information of Paula Dawson's three year Australian Research Council Discovery Project which draws on the case studies: Giotto Joachim and the Shepherds, (Padua, Scrovegni Chapel); Masaccio, Baptism of the Neophyte, (Florence, Brancacci Chapel) and a Drapery study by Leonardo da Vinci (London, British Museum) ,as analysed by Michael Baxandall in his book Shadows and Enlightenment, 1995.

Shadowy Figures tests the following ideas: Is it possible to transpose the way in which Giotto, Masaccio and Leonardo da Vinci used darkness in figurative representations into a hologram? Is it possible to recognize the differences between the three methods of using darkness in three dimensions ? and finally which of these styles of using darkness as an active agent of representation is most useful in conveying temporal effects?

To answer these questions it is necessary to view the hologram itself; however the quicktime VR provides a sense of the characteristics of the work. One third of the viewing zone of the hologram is devoted each to Giotto, Masaccio and Leonardo da Vinci. The treatment of lighting and darkness on the figure is entirely different in each of these zones so as to convey the particularities of Giotto, Masaccio and Leonardo adapted to full vertical and horizontal parallax.

The subject of the hologram is art historian John Gage who posed for a Cyrax laser scan as the draped figure in each of the case study art works. The entire process of making Shadowy Figures from initial drawings to final computed fringe digital hologram render is available on iDVD from the Ivan Dougherty Gallery.
