Watch Day And Night Unfold At The Same Time In This Trippy Video Of Boston

This is wild.

A new video from photographer Julian Tryba puts Boston in a whole new light, transforming the cityscape into beautiful bursts of pink, blue and yellow as day and night unfold simultaneously. Tryba calls the editing technique used to achieve this effect "layer lapse."

In traditional time-lapse videos, time progresses in a rapid yet linear sequence: Day quickly becomes night, and night melts back into day in mere seconds. But Tryba's layer-lapse video presents the passage of time in a non-linear pattern, stitching together shots taken at different parts of the day and layering them into a larger, otherworldly scene.

Tryba posted a blurb on Vimeo, describing the style:

Traditional time-lapses are constrained by the idea that there is a single universal clock. 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.

The photographer shot more than 100 hours of footage and spent another 350 hours editing to create the mesmerizing layer-lapse video of Bean Town. From the looks of things, it was time well spent.
