The foundation of phenomenological image theories is the view that image perception leads to a perception sui generis. In order to grasp this peculiarity of image perception, two ways have traditionally been considered: either through a description of the particular object of image perception or through a description of the unique origin of image perception. This article explores a third way within the phenomenology of the image by trying to determine the uniqueness of image perception through its peculiar, necessary effects on the observer of the image. The thesis is: The observer of an image does not become an image object in the image. It is only in the case of image perception that there is relief through a gap in participation. It is the perception of something without the demand, as the perceiving person, of being physically involved in what is perceived.
