The work explores the fleeting transition from autumn to winter through photographs of the same tree taken just a day apart. The dusting of blue sand applied to the branches becomes a key element of the composition, fulfilling a dual function.

The blue marker both reveals the hidden structure of the branches, turning them into clear graphic lines, and also plays the role of an indicator: the fact that the sand has not fallen off indicates the minimal time interval between the photographs.

Thus, the viewer observes an almost elusive moment of seasonal transition - a thin line between autumn and winter. The ephemeral nature of the sand emphasises the fragility of the moment and makes the work a kind of fixation of time slipping away.
