A Time Slice photo is a photo that combines many photos taken over a span of time in one image. Typically when I create my time Slice images I use vertical slices of uniform size to reveal the different photos. Wanting to create a little more different this time I decide to create a non uniform slice that changes over time. Day time photos are revealed in a different shape than the night photos.

I use Adobe After Effects to create the shapes that reveal the photos. This shape moves and changes over time.
