Filming of movie is not working for translating scenario of story or character's moving. Director of Photography accumulates emotion in scenario through image. The accumulation of continuation is the essence of movie. Therefore, cinematographer strives consistently to analysis scenario and to express through visual which operation of the most basis can be filming technology. Eventually, Filming of movie is based on mean of technology to show artistry work. Accordingly, searching the most fundamental of filming's technical factor considerably help to understand movie art. There are variation technology factors to expose character's emotion. And the most simple and influential try by only using the pure function of camera is utilizing shutter without supporting lighting and production design. As a result, this thesis discuss about essential and basic factors of utilizing shutter.

Upon ruling that two photographs of "Solsum(located in Samchuk city)" are not substantially similar, issues on the level of protection for the copyrighted photographs expecially on landscape, which appearance could be similar whoever takes, were raised. Accordingly, this study summarizes and suggests the standards of expression differentiating from idea on photographic works. The results are as such. Elements of expression on photographs are positioning of subject, framing, selection of camera angle, control of light's direction and quantity, length of exposure, speed of shutter, timing or posing of the shutter. kinds of emulsion, methods of development, and any other methods of creative and characteristic photography. On the other hand, elements of ideas of photographic works are theme, concept, feeling, appearance of objects, time or season of taking a picture, vantage point, choice of horizontal or vertical angle, etc. As a result, this study reconfirms that copyright law entitles photographers to copyright as to their minimal degree of creativity, not as to their sweat of brows.

The purpose of this study was to examine the putter head movement during the putting strokes. Highly skilled 5 golfers(less than 3 handicaps) and 5 novice golfers(having no golf experience) participated in this study. A target distance was 3 m. Movements of the putter head were recorded at 60 Hz with two video cameras(1/500 shutter speed). The results showed that the angle of the clubface of expert golfers was almost 1 degree, but the novice golfers were more than 6 degrees. Expert golfers moved their hands faster than the head movement, therefore the clubface was not opened during impact. However, the novice golfers moved their hands slower than the head movement, therefore the clubface was opened during impact. The ratio of input and output angles of total movement was 1:3-4, however, the ratio of input and output angles of impact zone was 1:2. The angle of normal vector of expert golfers was less than the angle of normal vector of novice golfers.
