Tecniche per la valutazione della qualità visuale del paesaggio rurale

The assessment of rural landscape visual quality can be used in order to define areas with a greater aesthetic value that have to be protected from a too much invasive human action. The most used procedures for landscape visual quality assessment are based on photographic test techniques: a set of photographs of the landscape are taken and then shown to a group of people that is asked to express an evaluation judgement for each photo. The present work intends to investigate more in depth the influence of seasonal changes and photography techniques on the evaluation judgement about the rural landscape visual quality. The work analyses the factors that can influence the evaluation judgement of the photos. The factor analysed are: seasons, weather conditions (sunny and cloudy), time of the day (morning and afternoon), camera focal length (28 mm, 35 mm, 50 mm and 80 mm), “photo composition”(background, middle ground and foreground). The judgements were processed in order to understand if and in which measure the factors analysed were able to influence the visual quality evaluation judgement. The work has demonstrated that the visual quality evaluation judgement is highly influenced by the season and the weather conditions, while doesn’t seem to be a clear relation with the camera and the “photo composition”.
