This study was carried out in order to determine what factors in slightly different photographs are influential when evaluating scenic coppices. For the analysis, a 450° photographs was taken with a rotatory camera. This photo was sequentially broken down into forty-seven photos of the coppice landscape. Each photo contains horizontal and gradual differences of the same location taken at the same time. Two questionnaires were then devised and distributed. The first was designed to establish categories based on compositional similarities. The second was designed to rate the photos based on the subjective comparison between each photo and its neighboring photo in the sequence. The results from the first questionnaire show that the five main factors used in determining the appropriate category for the photos are: 1) brightness, 2) main elements in the landscape other than trees, 3) conspicuous trees, 4) presence of artificial things, and 5) stand density. These factors are used in both independently and in conjunction with one another. The conclusion drawn from the second questionnaire is that the evaluation scores fluctuated according to changes in the horizontal constitution of the forest scenes. In addition, it shows that the five factors above played a key role in the evaluation process.
