| Abstract |
| The skin-tone in portrait photography is one of the most sensitive parts that need retouching by a photographer. To investigate the emotional reactions related to users` preferences for the skin-tone variations in portrait photography, two experiments were conducted. The first experiment included JND(Just Noticeable Difference) test to determine the general distribution of preferences with many photographs that varied in phases up to an extreme one, as a result, preferences for the brightest skin-tone and the red or magenta one were found. Based on the first experiment, we reduced the number of samples by adjusting their brightness to the brightest phase constantly. To intensify the second experiment, we reduced the number of the other colored samples to only one and made samples for five phases from green to magenta, namely the most preferred skin-tone in the first experiment. In the second experiment, the common preference for a neutral skin-tone and the partial difference between the two gender groups were found. In conclusion, the users` preference for a particular skin-tone was positively affected by emotions such as ``happiness`` or ``comfortable``. With this investigation, we compiled some statistically meaningful facts to confirm that the preferences of the users depend positively on controlling the skin-tone in portrait photography. |
