25 Time-Stack Sky Photographs Created from Time-Lapse Frames by Matt Molloy

Matt Molloy time-stack photography compresses long stretches of changing sky into a single image. The Canadian photographer creates the effect from time-lapse sequences, taking a photograph roughly every five seconds when conditions allow and then layering the frames in Photoshop. Because clouds and light move between exposures, the stacked result forms repeated bands that can resemble broad brushstrokes. One final picture may contain visual information gathered across several hours, showing a pattern the eye could not observe all at once in real time. The technique connects photography with digital assembly while keeping the source material grounded in an actual sequence of weather and light. This gallery presents 25 examples centered on sky and nature. Browse Matt Molloy time-stack photography to see how repetition, interval, and careful blending can turn a familiar sunset or cloud movement into a dense record of passing time.
