This article analyses the analogy between death (finiteness) and eternity (infiniteness) about reality of the photograph. Using photography that began with the act of creativity, as a tool for expressing yourself is in fact a struggle of human to get ahead of the concern of losing the things he/she values. Since it freezes the current time and takes it from life, it is a reflection of reality and has the quality of being eternal. All the photographs have the quality of being a document taken from time. It represents both death and eternity with its difference in presenting reality and eternalizing the current time. It is possible to interpret why photos remind us death, in different ways. According to Barthes, "this will happen and this was present" is the account for death. Likewise, for Susan Sontag, the concept of "memento mori" coincides with the fact of death. We can characterize photograph as something against death or as an opposition. It represents both death and eternity. Whatever the subject is, the object being taken in a photograph belongs to the past from now on. That is, it is dead. On the other hand, it becomes an immortal document by the person having taken the photograph.
