This study views the shadows cast by the light and a subject provides new interpretations rather than it simply being an additive product. Particularly in fashion photograph, light and shadows are often used as tools to convey meaning. Accordingly, this study aims to classify the utilization of the shadow created by light and deriving its expressive characteristics in fashion photograph. To achieve these research aims, literature and case studies were conducted. The results are as follows. First, the shadows were mainly focused on a subject. Secondly, shadows caused by lighting is casted directly into the inside of the main subject in a frame takes a role of omission or emphasis. Third, shadows caused by a second unseen object outside the frame are utilized with the main subject in the frame. Based on these results above, spatial third dimensionality, optical illusion and accentuation were derived as expressive characteristics of the shadow in fashion photograph. As such, in fashion photograph, shadow is an important element for photographers. The variability of the shadow makes it possible for creative changes as its amount, angle and direction can be altered by adjusting the light in accordance with the intention of the artist. Therefore, its utilization methods will be diversified hereafter. Accordingly, it is required to recognize that shadow may be recreated as an independent object in fashion photograph.

To analyze the spray and flame in D.I. diesel engine, the visualizing methods by schlieren photograph and diffused background illumination photograph with high speed camera are applied to optically accessible D.I.diesel engine. Wcaporating spray, spray droplets and brightness flame are taken with high speed camera by visuallizing method in accordance with various suction air temperature and injection time. The spray and flame image on the film was analyzed by image analyzer. The optically accessible D.I. diesel engine had the similar pressure characteristic to the real D.I. diesel engine. Experimental results showed that shadow areas of the evaporating spray were extended at higher suction air temperature, spray droplets had a max. Penetration length and their penetrating patterns were dependent on the surrounding gas temperature, and flame size after ignition was largely governed by the evaporated fuel quantity at ignition point and by the surrounding gas condition due to piston motion.

The National Geographic Information Institute of Korea takes digital aerial photograph images every two years to make and modify/renew the digital map. The cameras for aerial photogrammetry to capture these digital aerial photographs are divided into frame types and line types. Computer vision analysis of aerial photograph images was only possible for frame type. Thus, in this study, Line type aerial photograph images was intended to generate geospatial information through computer vision analysis, and forest geospatial information was created as a method for the utilization of aerial picture images. As a result, geospatial information generated by computer vision analysis of line type aerial photograph images showed that RMSE of horizontal and vertical position errors was less than quadruple that of GSD. Forest geospatial information was generated using geospatial information generated by computer vision analysis. It was confirmed that extraction of the crown of tree and calculation of tree height are possible. Through this study, it is expected that utilization of aerial photograph images will be improved.

In order to examine the material characteristics of a black and white photograph of the Borobudur temple, in Indonesia, several analyses were conducted. A sample was taken from a black and white photograph; microscopy, Fourier transform-infrared spectroscopy, scanning electron microscopy/energy dispersive spectroscopy, X-ray diffraction, and X-ray fluorescence analyses showed that the black and white photograph was composed of four layers including a paper substrate, baryta, binder and surface layers. It was confirmed that the substrate was paper made of cellulose fiber from Cannabis sativa, the baryta layer was made of barium sulfate(BaSO₄) in powder form, the binder was an emulsion containing silver halide, and the surface protective layer was made of gelatin. Since photographs have different characteristics and require different preservation environments depending on the material of construction, it is necessary to study various black and white photographic material characteristics corresponding to each time period.

The purpose of this study was to investigate the effects of the types and the colors of men's casual wear, hairstyles, and the methods of stimulus manufacture on men's image perception. The subjects were 360 women from the metropolitan area of Seoul. The clothing types used for the study were a sweater and a jumper(casual jacket) with jean pants. The clothing colors were beige, indigo, and red. Two hairstyles, the short and the medium length hairs, were compared. Two types of stimuli, the photograph and the computer simulation picture, were used. The results of the factor analysis disclosed five dimensions on men's image: neatness, individuality, ability, activity, and sociability. In general, the photograph stimuli were evaluated more positively in activity, individuality, and sociability than the picture stimuli. The sweaters were perceived higher in ability, activity, and sociability than the jumpers. The Indigo color was evaluated as neat. The medium length hairstyles were perceived as neat and the short hairstyles were perceived as sociable. The jumpers were evaluated lower in individuality in the picture stimuli than in the photograph stimuli. The beige and indigo colors were evaluated to be neater in the picture stimuli than in the photograph. When using the picture stimuli, the men's image wearing the sweaters with the medium length hairstyles were evaluated lower in individuality. When using the photograph stimuli, the men's image wearing the sweater with the short hairstyles were evaluated higher in activity. Men's image wearing the indigo jumper and the beige sweater with medium length hairs were evaluated as high in neatness.

Describing the filmography of Yong-ho KIM simply in a few sentences is considered nearly impossible. For the last 20 years and longer, KIM has been building up his career energetically as he never lets himself obsessed with any particular boundaries or areas but work on everything from paper advertisements to art galleries, advertising photographs and pure photographs. The Photolanguage personally mentioned by Yong-ho KIM himself is to visualize this imaginary story in a form of photograph, which one would come up with before shooting. When it comes to the advertising photographs, since they are used basically to sell products, they are considered rather temporary, and in addition, they photograph the products mostly under these bright lights with colorful backgrounds behind. However, Yong-ho KIM was recognized for presenting very much different work as he went even beyond these old stereotypes of the advertising photographs. The advertising photographs processed by KIM do more than merely introducing details or functions of some products, but they deliver these values and cultures that consumers can enjoy and gain through these original stories about the products. Of several pieces of KIM's work, this advertisement on Hyundai Card named was invited to an exhibition by a private gallery after the work was exposed through various media. The work was even purchased, and that was something that had not happened before in the history of the relevant field. When a photograph is purchased, it makes the photograph recognized for its value to be possessed, and when a photograph is displayed, it, again, makes the photograph win recognition as an art work. This thesis discusses the Photolanguage found in the works of Yong-ho KIM, one of the most well-known advertising photographers in South Korea. The research inquiries that have been analyzed in the body of the thesis, therefore, are the photographs and language in the digital era, the story-telling advertisements and these works by Yong-ho KIM.

Among components of digital topographic maps used officially in Korea, only contours have 3D values except buildings and trees that are demanded in landscape planning. This study presented a series of processes for 3Dreconstructing landscape features such as terrain, buildings and standing trees using LiDAR (Light Detection And Ranging) data and aerial digital photo graphs. The 3D reconstructing processes contain 1) building terrain model, 2) delineating outline of landscape features, 3) extracting height values, and 4) shaping and coloring landscape features using aerial photograph and 3-D virtual data base. LiDAR data and aerial photograph was taken in November 2006 for $50km^{2}$ area in Sorak National Park located in eastern part of Korea. The average scanning density of LiDAR pulse was 1.32 points per square meter, and the aerial photograph with RGB bands has $0.35m{\times}0.35m$ spatial resolution. Using reconstructed 3D landscape features, visibility with the growing trees with time and at different viewpoints was analyzed. Visible area from viewpoint could be effectively estimated considering 3D information of landscape features. This process could be applied for landscape planning like building scale with the consideration of surrounding landscape features.
