A photograph is an act of making an object intervening in a four-dimensional space-time that constitutes the real world into a two-dimensional plane, and a moving image is an act of making a four-dimensional space-time into a three-dimensional space-time. Both can be said to be expression methods that reduce the dimension of the expression subject of free space-time in a form that is constrained by the dimension peculiar to the recording medium and fix it on the medium.


Photos and videos are differentiated only by the method of handling time dimensions. In videos, time dimensions are sampled and recorded at regular intervals, but in photographs, time dimension samples have an extremely high degree of freedom at the will of the artist. It is possible to make it. In particular, super-time exposure in a photograph is an act of condensing a time dimension expressed as a continuum of two-dimensional planes in a moving image into a unique plane, and can be said to be a means of expression peculiar to a photograph.

In the process of condensing and disappearing the time dimension by super-time exposure and making it a two-dimensional plane, we try to add a virtual dimension by intentionally sweeping the expression subject. That is, the expression subject that is made into a two-dimensional plane from the four-dimensional space-time by the act of photography is made into a three-dimensional three-dimensional. It can be said that it is a three-dimensional photographic model that is embodied only by the act of photography.

Certainly, the two-dimensional illuminant that actually existed was sublimated into a photographic three-dimensional object by the act of applying a sweep at the time of shooting, and now it is in front of me as a photograph. "It used to be there," but at the same time, "it wasn't there." Looking at these three-dimensional photographic solids, I don't feel like deeply appealing to what the reality and recordability of photography are.
