Abstract
Abstract. Digital photography is a method easily employed to capture images. Mobile devices such as smartphones and tablets as well as dedicated cameras are used to capture images. Furthermore, as hardware continues to improve, the resolution of images in 100 MP and 8K videos has recently been increased, and the quality of images enhanced through various types of image processing software. However, because the focus of photography is to record a moment activity, recording the orginal color of subject has been pushed back from priority. Digital photographs of cultural heritage are mainly captured for aesthetic appreciation and database construction. Those images for the purpose of the latter should record the exact color and shape of the subject. However, the theoretical approach of this is difficult and relatively complex procedures are able to create images that differ from the original color. Thus, it means falling in value that culture heritage data of important for color conservation. Various attempts have been made throughout the industry to capture the original colors of the subject accurately. The color management system (CMS) is a typical method of such. In this study, digital color reproduction and record studies were conducted on representative oil paintings of modern times in Korea. Accordingly, the light source’s color index and color temperature were measured. Furthermore, a color recording environment was established and digital images were acquired. Subsequently, it was able to record the original color through CMS-based image processing. It is believed that this study will enable one to understand the production techniques of works through the color record of oil paintings and help one to monitor conservation conditions such as discoloration.
Highlights
Digital photography is an accessible and widely used method that can record a moment activity
Image processing was subsequently performed based on reference colors
Image processing such as exposure, white balance, brightness, and chromaticity was performed, and color reproduction could be completed through color space setting of the color correction completed images
Summary
Digital photography is an accessible and widely used method that can record a moment activity. Images intended for cultural heritage databases should record the exact color of the subject. This is not always easy to apply digital image processes. Digital color reproduction and documentiaion were conducted for the Korea's modern period representative oil painting. To this end, after measuring the capture environment and establishing color recording conditions, digital images were acquired. Using CMS-based image processing, it was able to accurately reproduce the original colors of the painting. It is believed that this study will enable to understand the production techniques of works through the color record of oil paintings and help one to monitor conservation conditions such as discoloration
