은염과 디지털 도구에 따른 조명비 교육의 실제 적용에 관한 연구

Abstract

Photographers deal with light in the limited area of visible ray and the difference in techniques to treat the given light makes difference in works of them. They sometimes have to determine the directions, angles, colors, and quality of light. Also, they know there is lighting ratio in any light that reaches subjects in any situation. The most difficult part of taking pictures in digital environment is that the rule of lighting ratio appled when using silver halide(film) to create the desirable mood is not adequate. Thus, I reviewed a thesis on this part as a preliminary study and found out that when the ratio of highlight and shadow are 1:1, 1:2, 1:4 the results of silver halide were nearly similar with those of digital but the depth of shadow of digital turned out to be opposite in case of 1:8, 1:16, 1:32. In case of digital, I could get results of lighting ratio learned in silver halide only when l took pictures with sequentially reduced light intensity of fill light so that it might be less than the value of lighting ratio indicated on exposure meter, comparing to silver halide. Therefore, this study intends to review the phenomenon and value of education appeared when the results of preliminary study were applied to lighting education. The education was implemented, divided into two groups; one group that experienced the results from the process of comparison experiment of silver halide and digital in real education were different and the other group that didn't. In addition, I intended to understand the difference in representation properties of silver halide and digital and present the necessity of differentiated and proper approach toward lighting ratio education by analyzing results through questionnaire survey.
