“…Research in areas such as forestry, architecture and urban design [1][2][3] have established that images can be a reasonable surrogate for the real space, particularly on ratings related to aethestics. The limited research in lighting on this topic concurs with this, when representing the real space with photographs 4 , or with highly-detailed simulations 5 .…”

The image was projected onto a screen at realistic luminances and 54% of full size. The images in the series were geometrically identical, but the luminances of important surfaces were independently manipulated. Initially, the combinations of luminances were random, but as the session continued a genetic algorithm was used to generate new images that generally retained features of prior images that were rated most highly. As a result, the images presented converged on an individual's preferred combination of luminances. The results demonstrated that this technique was effective in reaching a participant's preferred combination of luminances. There were significant differences in room appearance ratings of the most attractive image compared to other images, and the differences were in the expected direction. Factor analysis of ratings of the most attractive images revealed a factor structure with some similarity to that obtained when people rated real office spaces. Furthermore, preferred luminances were similar to those chosen by people in real settings, as was the variation in preferences between individuals. Journal of the Illuminating EngineeringFinally, subjective ratings of brightness, uniformity and attractiveness were significantly related to luminances in the image.

R.; Richardson, C.; Blanchet, C.; Veitch, J. A. AbstractForty participants viewed a series of high-quality, colour images of a typical open-plan partitioned office, and rated them for attractiveness. The images were projected at realistic luminances and 33% of full size. The images were geometrically identical, but the outputs of four lighting circuits depicted in the renderings were independently manipulated. Initially, the lighting circuit outputs were random, but a genetic algorithm was used to generate new images that retained features of prior, highly-rated, images. As a result, the images converged on an individual's preferred scene. Luminances in the preferred image were similar to preferred luminances chosen by people in real settings. A sub-set of images was rated on Brightness, Non-Uniformity and Attraction scales. Ratings were significantly related to simple photometric descriptors of the images. In particular, around 50% of the variance in Attraction ratings was predicted by average image luminance and its square, or by average image luminance and a measure of luminance variability.

“…These were derived from a larger set of 27 scales commonly used in lighting research [e.g. Hendrick et al 1977], and which have often been successfully abridged [e.g. Mahdavi and Eissa 2002; Newsham et al 2005].…”

“…In lighting research, visual representations of spaces and scenes, presented in a variety of ways, have been used for evaluation purposes. Hendrick et al [1977] conducted early work using projected images from photographic slides. Students completed semantic differential ratings of six scenes (a non-daylit conference room lit in different ways) after viewing each one for 30 seconds; they did not observe the real space.…”

The scenes were viewed in three presentation modes: participants saw the real space, and images of the spaces on a 17-inch computer monitor in both conventional and high dynamic range (HDR) mode. HDR mode allowed the high range of luminances in the real scene to be accurately reproduced, with maximum luminances more than ten times higher than those in the conventional images. For those participants who saw the images before the real spaces (the most relevant order for practical applications), the HDR images were rated as significantly more realistic than the conventional images. However, this effect was limited to scenes with relatively large areas of high luminance, which in this study was represented by scenes with windows and daylight. Ratings of the HDR images were significantly related to simple photometric descriptors of the images in the expected manner: brightness and glare ratings were positively correlated with overall and elevated luminance, and non-uniformity ratings were positively correlated with luminance variability. These results suggest that for evaluations of visual appearanc...
