The basic building block of "An hour and a day" is simple, mundane even: a shot of an airplane in flight, crossing from one side of the frame to the other. Some planes are fast. Others are slow. Some appear as small as fireflies off in the distance, while others soar just overhead. Trajectory after trajectory has been sequenced into a meticulous montage according to the exact time of day it was filmed, regardless of which day it was shot.
The video compresses time, spanning from early morning to late night, as shifts in light reveal the passing of time not only over the course of a day, but also throughout the year. So what presumes to be a straightforward dawn-to-dusk equation eventually breaks down as afternoon turns into a dark February night, which shifts into a glowing August evening and then back into darkness once again.
In much the same way that one keeps a daily journal, I continue to collect this footage, shot from my kitchen window since January 2008.
