利用攝影媒體表達景觀空間之研究

A Study on the Use Photographs as a Medium to Present Landscape Space

利用攝影媒體表達景觀空間，不能過於藝術化，要以真實的眼光雲記錄景觀，並且要包括景觀中的大部份因素。本研究是利用景觀空間作業方法中的視野圖（view shed）來比較觀賞者位置、觀賞距離、觀賞角度等與攝影鏡頭主攝影取景之關係，並建立不同拍攝法所行到景觀空間照片差異比較之資料。由於景觀研究之目標不同所採用之取景及攝影工具亦有相當大的彈性。廣角鏡頭較能表達整個可視景觀的空間架衍，因此常用單張廣角照片來表達景觀的空間層次；標準鏡頭較能表達近景及中景之細部，因而常用於景觀美質研究及細部之表達，利用50mm拍行三張連接之照片可彌補視角之不足，並可充分表達出近景及中景之景觀美質。

To use photography as a medium to present landscape space one must record landscape truthfully, including most of their elements. This study analyzes visual landscape and view shed. It also discusses the relationship between the landscape distance zone, the point of view, and the view width; and camera lens and focal landscape. The data will he recorded by different types of photographs. There is a large flexibility of photographic technique and method. This is needed to suit the different aims of a landscape study. Wide-angle photographs can present the visual landscapespace frame better. 50mm lens photographs, printed, present middle scene and close-up scenes better. Three pranoramic prints (50 mm lens) can compensate for the 50 mm lens' lack of view width. They thus make a good presentation medium for describing a landscape quality.
