Abstract The influence relationship of professional and amateur photographers, which has sustained for about 150 years, has been changed as the digital technology has grafted into photography, the digital camera developed, and its massive propagation. Particularly the economical sphere, the strong influence of amateur photographers have threatened professionals. One has to learn various camera techniques to be a professional photographer before the digital technology has grafted into photography. It's digital cameras that emancipated amateur photographers from many sophisticated works to take long efforts, collapsing the high technological barrier that amateurs have coped with. It is not an exaggerated statement that the change of the photography field is that of digital cameras. The intension of and attitude to the acceptance of digital cameras would be the important condition for the present and future of photography. While the studies of the intension of accepting digital cameras have been on amateur photographers as prosumers so far, this study's objects are professional photographers, whose intention of and attitude to the acceptance of digital cameras. This study shows that the simple technological progress has determined boundary of professional and amateur photographers in term of professionals' aspects with the related cause-and-effect variables, particularly economical ones. The result of this research shows that professional photographers' choice to use digital cameras are based on their easinessㆍself-efficacyㆍreceptive intentionㆍexperience rather than their usefulness, while they have little interest in the economical reason to use digital cameras, in which amateur prosumers have highlevel interest.

This study aims to discuss the impact that using colorless transparent lenses has on image quality. Such impact was analyzed and evaluated based on the resolution and color changes that occurred due to having filter mounted to the equipment. Furthermore, the significance of coating, which is often advocated by filter makers, was analyzed. The results showed that the price of filters is not proportional to its value (changes in image quality). Also, another significant finding was that using filters resulted in worsened image quality. A coated filter is shown to have no direct impact on image quality. Because a filter is placed at the forefront of the lens and even if light is reflected, the reflected light rarely enters the interior of the lens, it can be said that image quality is not affected by coated filters. However, if UV light directly hits the filter, flare can occur thus it should be used with caution.

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.

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.

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.

안시준 ( Si Joon An ) 한국사진학회 2013 AURA Vol.0 No.30

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.
