This study aimed to establish the methods both of recording natural phenomena, which are familiar for us but are difficult to recognize in our ordinary life rhythm, as primary image sources, and of editing and utilizing those primary image sources as secondary image sources.In order to visualize those natural phenomena, the diurnal variations in light conditions at forest floors in climax warm-temperate evergreen broad-leaved forests as short time scale phenomena, the continuous quantitative changes in a water of an irrigation pond by a yearly drainage as middle time scale phenomena and so on were tried to record as primary image sources by using the interval-photograph technique. Further, those primary image sources were tried to edit for representing such natural phenomena are perceived.
