RGB기반의 사진이미지를 오프셋 인쇄로 출력할 때 색역의 차이에 의한 색 손실이 발생하는 것은 상식이다. 따라서 사진가는 사진을 인쇄의뢰 할 때 일정정도의 색 손실을 감안하고 인쇄를 시행해야 한다. 이때 원본과 최대한 가까운 결과를 얻기 위해 시행하는 작업이 교정이다. 이러한 교정은 디지털기술이 도입되면서 관리가 용이해졌다. 즉 교정에 디지털장비를 사용하게 되어 교정의 질을 일정하게 유지 관리할 수 있게 되었다. 본 연구는 이러한 교정에 관한 연구이다. 기존에도 교정에 관한 연구가 있었지만 이는 인쇄분야에서 시행한 연구로 인쇄소 시스템을 기반으로 하고 있다. 즉 사진가가 거의 사용하지 않는 인쇄용 립(RIP)과 고가의 인쇄전용 장비를 필요로 하는 연구이다. 따라서 사진가 스스로 자신의 기준에 맞춘 교정을 시행하기 어려운 실정이다. 본 연구에서는 사진가가 직접 사진용 시스템을 이용하여 교정 작업을 시행할 수 있는 방안을 모색하기 위해 시행하였다. 즉 사진가가 주로 사용하는 포토샵 프로그램과 사진용 잉크젯 프린터 그리고 사진용지를 이용한 교정에 관한 연구이다. This study on the proofing what used to correct the color difference between the photo image and offset press. Printing photos with color offset press always make the differs, because of the difference in gamut. Photographer hopes to be able to use the proofing with inkjet printer for reduce these differences. In this study, I experiment with various ways for the proofing by photographer directly. It is using the ink jet printer and image outputs of the various mode was applied to a variety of color setting value. And calculate the output image using a spectrophotometer and compared with the image of offset press. At last I can found a very similar color setting value with the offset image. After all this research is to obtain a result of finding out proofing work flow through method to measure and how to apply various color setting value results.

The reproduction and preservation of monitor is relative important in dealing with digital photograph. Unfortunately the monitor according to the maker and the model represents much difference in color reproduction and preservation. To solve this problem we need to apply CMS (Color management system) matching the color among different devices. In particular, optical device is used for calibration of monitor. It is known as common sense to preheat the monitor around 1 hour before calibration, which makes colors of monitor displayed stable. However technical progress regarding monitor might demand the change of time witch be taken colors to be displayed stable. It make the change in the time condition regarding monitor and in period for monitor to preserve colors. On this study we consider how much the reproduction of color is affected by the time which monitors that normally used display stable, which means sufficient conditions to apply calibration, and how the color is changed with time after calibration. On this study we hope that we find the performance of monitors on view of user and supply the material to manage calibration.

The news photography which is used to newspaper medium basically the photo for a medium be undergoes the influence which is a directness to change of medium because. By the change of the namely media currently the newspaper photo is being put to request of reform. The namely digital communication technique develops, creating and consuming of news from this paper printed matter moves is quickly with the digital network namely internet. Smartphone participating which from 2009 is supplied specially with high speed is really dazzling. As for such environmental change the newspaper photo as for under photographing is becoming the biggest threat to the photographer. From the newspaper publishing company the cameraman who majored the photo hires does not do any more. Also becomes larger day by day and the newspaper publishing company true meaning portion by the photo specialist with effect of the internet newspaper is decreasing. The photographer pursues consequently to change of such environment in order to grope the direction which will do. Examined the direction which through Internet Homepage analysis of the newspaper publishing company the pro report photographer will aim specially.

조명환경에 따른 색인지 특성에 관한 연구

The color is determined and the illumination is known in the environment printing the photo as the important factor. Particularly, the illumination which is similar to the sunlight is the standard illumination. Therefore, in the light maker, the illumination surrounding which is similar to the sunlight is made and it sells expensively. In case of using the sunlight uniquely this is based on the logic in which the perfect color determination becomes available. However, the sunlight changes always. And the human had been adapting always to that change. That is, even if the characteristic of the illumination is changed, it can recognize as the same color through the chromatic adaptation. This research made a study whether the general artificial light source reached any effect on the color determination or not. In addition, in this research, the relatively color valuation was implemented through the color comparison. There a kind of illumination the dollar was no problem in the color awareness in case there was the research result sample. In addition, the metamerism was not generated in this experiment environment experimented with the inkjet printer using the pigment ink. Therefore, if the sample picture is provided in advance when printing the result photo of this research, it is no problem of the color, the work is possible in most of illumination surroundings.

Photographs are discolored by the time. Faded photos are not good for viewing, and they also decline in commercial value. Conventional color photographs showed discoloration in a short time. So the art photograph was not expensive art. Therefore art photographs have a higher proportion of black and white photographs than color photographs. Now, however, most photographic works are printed with durable pigments. Even the manufacturer advertises the 200 years as lifetime of the photograph. In this study, we investigated whether the lifespan of a color photograph, which was thought to be short in the life of the photograph, was actually extended due to the use of pigment ink. Especially, the durability of paintings and photographs are compared. Compared with pigment ink used in photography with oil painting inks and acrylic inks used in arts. The results of the study show that the photographic prints used pigment ink have the same durability as the oil painting. In addition, the degree of discoloration is very low for images protected with acrylic or glass. Now, photographs can be viewed as a genre that can be enjoyed for a long time while maintaining the image quality as oil paintings.

In these days applicants for the college have reduced compared to the numbers of entrants, as figures show. Particularly the departments of photography have that tendency in a serious level, only to get worse. Therefore most colleges and departments are in the strong need of their efforts in students supply and demand. The balances in students supply and demand are very important in the management and development of colleges. Thus colleges have made big efforts to supply students. And this effort would get strong, making colleges hyper-competitive. This competitive school environment results in excessive publicity activities. Therefore, the publicity information has to target applicants as consumers; the education better meet the needs of them. The study is the analysis from the dada of the choosing criterion and the preference and demand for universities shown by high-school students who have chosen photography. Thus, this study has the significance of the base material for the effective publicity information and the proper education direction, accounting for high-school students who have applied for photography departments.

This study on the study of Craftsman photography qualification. In most field, except for art photography photo to pursue the industrial value. Industrial, economic, and technical qualifications of individuals in the labor market is an efficient tool to evaluate the ability. Field of current photo only the lowest level of the qualification system "Craftsman photography qualification" system operating. Thus, the field of photography more than the mid-level skills assessment and objective criteria are not formally prove that. So the industrial sector will increase in value of the current picture, so a rise in national discussions about the grade oftechnical qualifications are needed. In general, technical qualifications have great influence on the education system. Some universities, especially engineer or Industrial Engineer certification course aims to educate. Because of the reduced number of current high school students within the state Department of Education technology assessment efforts have included the relevant qualifications. This study on these contemporary demands, rising field of photography for the purpose of national technical qualification grade was conducted. Method of study is surveys and analysis the opinions of educators teaching photo at collage and university.
