How Photographic Image-quality Affects the Sense of Time of Viewers

Optical construction of images, namely in image-quality, effects the mind of a viewer. Therefore, film, TV, and photography professionals create images to affect viewers' emotions and feelings. We investigated how this type of image quality effects the sense of time of viewers. In experiment I, impression evaluations, using the normalized ranking method, were conducted on images that had been digitally processed to create different types of image-quality. The results show that the color of images is largely concerned with the sense of the past. In experiment II, we evaluated the impression of time of monochrome images that had been digitally processed, creating different colors, to investigate the effects of these hues with regards to the viewer's impression of time. In experiment III, we evaluated sepia toned images, which roused a strong sense of the past in the viewers. It was found that chroma, especially sepia, plays an important role in the sense-of-the-past feeling of the viewers of these images.
