131 photos merged into one image using the lighten layer-blending mode in photoshop. Even though all these photos are in the previous photo, you don't see much of their influence because most of them are darker than the photos from the begining of the timelapse. I wasn't sure which version I liked better so I uploaded both. This gives you an idea of how different time-stacks can look when you don't use all the photos from a timelapse. That's why I stack all the photos first, and then try less and less to see what works best. It's all about finding that "golden section" of a timelapse.
