Study on the Evaluation of Shadow Puppetry Performance Effects Based on Lighting Environment Impact
The evaluation of the visual effects of shadow puppetry is of great significance for improving performance devices and enhancing performance effects,yet no scholars have conducted research on this topic to date.In this study,a psychophysical experiment was conducted with 32 subjects under 16 different lighting environments.Subjective evaluations were obtained for three visual attributes:color vividness,detail clarity,and expressiveness and attractiveness.The correlation between lighting parameters and subjective visual evaluations was analyzed.Preliminary research suggests that a color temperature of 3 500 K is optimal,with a 100 W incandescent light source being the best among white light sources.For LED light sources,the subjective evaluation is highest when the illuminance reaches 200 lx at a color temperature of 2 800～4 500 K.LED light sources with a color temperature above 5 300 K require higher illuminance levels.A linear combination of illuminance and GAI_BB_8 can effectively evaluate the visual presentation of shadow puppetry performances.The research results preliminarily establish the optimal lighting conditions for shadow puppetry performance under different light environments,providing reference for the quantitative evaluation of the visual effects of shadow puppetry performances and the improvement of performance devices.
