Abstract

We found that a mountain appears taller when observed from a position that is higher than the mountain’s height. Observers were first asked to look at photographs of mountains taken from various heights. They are then made to compare each of the photographs (standard stimuli) with the comparison stimuli, which comprised of images that had been digitally expanded or reduced in height as compared to the original photograph taken from a certain height. Subsequently, the observers selected one of the comparison stimuli where the height of the mountain in the standard stimulus appeared to be the same as that of the processed image. The results indicated that mountains appeared the tallest when they were observed from a height that was 1.4 to 1.7 times higher than their altitudes.
