흑백과 컬러 사진에서 깊이 지각의 차이

Abstract

Expression of depth is one of the most important factors in constructing the creative vision of a photographer. To emphasis the feeling of depth, photographers tend to choose black and white processing. This is because there has been a myth: color photography is flatter than black and white. This experimental study is performed to investigate the effect of the presence of color as a photographic technique on depth perception. The stimuli were taken in color using major factors in changing depth impression, which were then duplicated and transformed to gray scale images. In the result, the smaller aperture size and the longer focal length decreased depth perception in both chromatic and achromatic images. Color severely decreased depth impression at variations of focal length. In the mean time, the flattening effect of color was relatively weak along aperture variations. This implies that spatial frequency is a strong factor in giving a feeling of depth even in color photographs. Black and white process is still common in the field of photography as fine art. From the results of this work, the relatively intense feeling of depth can be one of the reasons for that.
