This work is part of the research process on the representation of time that began with my work 40 hours. Through urban views of Prague, this work is an attempt to represent time in photography.

In order to make this representation meaningful, the shots were taken with a pinhole which is a simple camera obscura incorporating a photosensitive film. This technical process was chosen because it allows naturally and easily to have particularly long exposure times. The camera obscura does not have a lens and the light enters inside only through a 0.18 mm diameter hole on one of its faces, requiring a much longer exposure time than a traditional camera. To increase the exposure time, the views were taken at night in order to limit the effects of rapid exposure of the film to daylight. Finally, the silver technical solution made possible to further increase the exposure time given that above 1 seconde, exposure times of photosensible film require overexposure to comply with the laws of reciprocity.

The shots are separated into two distinct series to have a representation of the two different mood and perception of time during night. The first series is dedicated on static elements and the second on moving subjects.

In the first series, the scenes show places devoid of any presence. Urban lighting generates refractions on the small pinhole opening in the form of diffuse halos. The atmosphere that emerges from these shots is a feeling of calm and peace where time seems suspended. Contrary, in the second series, moving elements emitting or reflecting light are integrated into the views. The movement of lights creates a persistence in the form of a light trail, thus formalizing time.
