| Paintings in the museums are displayed under various lighting conditions: day light, florescent, incandescent or more recent LED illumination. New computer controlled LED lamps [Zukauskas et al, 2012, Opt. Expr. 20(5), 5356-5367] could create safe light for paintings, simulate lighting conditions under which the painting was painted or create colour enriching illuminant which provides the most pleasant viewing experience. The present study was aimed to examine aesthetics of the paintings illuminated by computer controlled LED illumination. The LED lamps were installed at the M. K. Curlionis National Museum of Art to illuminate paintings with different condition: some were in good condition and others had changes in colour because of aging process. Through computer interface viewers were allowed to modify qualitative lighting parameters such as correlated colour temperature, saturating-dulling ratio and shift white light from Planck's locus. General public viewers and art experts were asked to customise LED lightning to increase visual aesthetics of the paintings. Art experts were asked to customise LED lighting to enhance colours for colour depleted painting. Results show that the viewers tend to enhance colour gamut for both types of paintings to achieve more visual pleasantness. [Supported by the Research Council of Lithuania MIP-098/2012] |
