The word "Nagi - Lull" here refers to the sway of silence, not to a state of stillness.
It may be explained if we look at it from the angle of 1/f fluctuation, but if we assume that human experience and sensory system can be quantified, we should be able to describe the existence of the symbol of fluctuation in a more concrete way.

However, since it is not possible to see the fluctuation as "movement" in the realism of the "subject" itself that the photograph captures, we will experience the "fluctuation" in a still image or in a series of images.
The visual fragment (piece of continuity) of this symbol, or "fluctuation," is called "Nagi-Lull".

As an explanation of the decomposition of the fluctuation, the intersection of the vertical and horizontal axes of the flow of time and the continuous existence of space has been extracted by experience or by quantification, and this is taken as a form or image of fluctuation, and is called "Nagi-lull".

In other words, it may be like spinning out flowers, birds, wind, and the moon as "the state of things”"Mononoaware"(appreciation of the fleeting nature of beauty).

This "texture" (qualia) tends to be treated as a traditional aesthetic sense unique to Japan.
However, it is a feeling that is expressed as an individual's mental landscape through the filter of sensitivity from the environment and space surrounding the "person.

And I would like to believe that this is an instinctive reaction of human beings.
In other words, understanding art in context alone will not satisfy our aesthetic instincts.
It can be said that the concept of "Zero-horizon Photographic Art" is a concept that is located in a horizon that is distinct from such a systematic context.
