I noticed a salt barn and approached it taking pictures. But as the real object came into view clearly, that was not the same as I expected. What I believed a salt barn was a bird observation deck. I print photos and build up them through piling up a copy by copy orderly. From the camera table, a camera keep an eye forward the photos out of focus. As time passes, photos come closer to its lens as thick as they pile up. Ultimately about 500 photos, congealing memories as if they metaphorize the trajectory of consciousness, turn back on such a subjectivation, ambiguity. The stack of photos proves that it is not a salt barn what I tried to remember, and becomes a mean by which the incompleteness and ambiguity are revealed.
