This Layer-Lapse of NYC Merges Night and Day

The former rocket scientist turned filmmaker Julian Tryba made an extraordinary time lapse that combines math and art with stunning results. Experimenting with time and space is an exciting premise for a video art project.

Using some incredibly intricate and careful masking, Tryba allowed different times of day and night to flash across different buildings, but didn’t stop there. Next, each building was assigned a unique mathematical equation and parameters that told it which time of day to display, often using random sinusoidal functions to create oscillations within each building in addition to the global behavior (think of this as a shimmer). Finally, the video was linked up with a beat map of a piece of music to coordinate to changes in the sound, creating the amazing final product you see in the video.

“Traditional time-lapses are constrained by the idea that there is a single universal clock,” Tryba writes. “In the spirit of Einstein’s relativity theory, layer-lapses assign distinct clocks to any number of objects or regions in a scene. “Each of these clocks may start at any point in time, and tick at any rate. The result is a visual time dilation effect known as layer-lapse.”

To make this mind bending time lapse, Tryba took 22 trips to New York for 352 hours of filming and over 200,000 photographs captured. That added up to almost 10,000 miles driven and $1,430 in parking fees.
