ICC 프로파일 적용에 따른 니콘과 캐논 카메라 로(Raw)파일컬러 영역에 관한 시 감각적 연구

Abstract

Raw file is known to have a variety of information. Therefore it is possible to match the colors as similar as possible and I planned to check how it was perceived visual sensitively. I conducted this experiment using Nikon D800E, Canon 5d mark3, Nikon 24-70 lens, Canon 24-70 lens, 2 Samyang 35mm Nikon and Canon mount lens. And I took the portrait photographs of a man and a woman, color chart and color chart SG in files. Using this color chart through Color checker passport program, I produced profiles with my camera. In addition, color profiles were made using color chart SG through Eyeone Match. With this profile, I looked visually check the survey responses do. I conducted a survey on how variables of camera, lens, program, and profile development affect visual sensitivity and its responses. And I also checked how the camera profile production can make effective profile. In this study, it should be noted that it was reconfirmed decisions on exposure were different in neutral color for Nikon and Canon camera and controls on those matters were carried out. Conclusions from these experiments are as follows. In order to sustain the exposure value as neutral color as neutral color, approximately one third stop of exposure difference occurred between Nikon and Canon camera nearby neutral color area. It was possible to produce color that did not differ greatly visual sensitively in studio photo shoot when the exposure difference was adjusted to make it even. 59 photography major students participated in the survey. The survey showed portrait photographs and color chart photograph and asked them how much tone difference there was between the two photographs. The possible answer choices were as follows in the survey. 1=There was much difference in tone, 2=A slight difference, 3=Almost no difference, 4=No difference at all. The reason for choosing portrait photograph's tone is because people's skin tone responds sensitively. When profile wasn't set-up, survey results showed that there was a slight difference in tone. However a file with a profile showed almost no difference in the survey results. This confirms that variables in profiles affected more than lens variables. The survey result also showed that degree of classification on color was not a big variable when using Nikon, Canon, Samyang and exclusive lens. There was almost no difference of eyesight between men and women. When SG chart was used to create a profile, it showed the least difference in the survey results.
