이미지에서 조명의 명암 비율 차이에 따른 감성의 변화

초록

This research, as a follow-up study of " the research on sensitivity vocabulary subsequent to lighting location in image." conducted a measuring experiment of vocabulary preference by applying Semantic Differential Theory to a human being's sensitivity change incurred by the difference in the ratio of intensity of brightness & darkness of key light and fill light of illumination of image. For this purpose, this research made 5 images by dividing the intensity ratio of lighting into 5 stages and drew up a questionnaire by applying "7-point Self Assessment Manikins" on the basis of 11 pairs of vocabularies coupling with their antonyms, then doing experiments on 46 subjects. The experiment results of this research are as follows: First, as for average standard deviation between man and woman, there appeared no specifically big difference between genders though woman's average standard deviation[SD.=1.54] generally came out a little less than man's[SD.=1.58]. Second, except the lighting intensity ratio of 1:16, the minimum average standard deviation of most of the lighting intensity ratio appeared colorful-simple, while the maximum average standard deviation appeared static-dynamic. Third, as for the change in lighting intensity ratio and sensitivity vocabulary preference, there showed an increase in a regular sequence as against all lighting in the survey of sensitivity vocabulary, such as light -heavy, and horrible-tranquil, etc. and there showed a sequential increase and decrease in all lighting ratios but 1:1 lighting ratio surveyed in the sensitivity vocabulary of tender-wild, positive-negative, and comfortable-uncomfortable. Fourth, there showed the best preference for sensitivity vocabularies in the five words- light, tender, positive, comfortable, and tranquil in the lighting intensity ratio of 1;2 while there showed a preference for sensitivity vocabularies in total of 4 words- horrible, negative, wild, and uncomfortable, etc. Considering the final results of this research, it appeared that the difference in lighting intensity ratio generally had an effect on a subject's choice of sensitivity vocabulary preference, and such cases were quite commonly found out, especially, in the ads assuming a negative aspect, such as 1:2 lighting intensity ratio did in the ads of cosmetics, department store and wrist watch, while 1;16 lighting intensity ratio did in posters on horror movies, ads on public benefit(non-smoking)and temperance, etc.
