Timestacks are exactly what they sound like. Multiple photographs taken over a period of time are layered together and blended to produce a single image. The magic behind this lovely effect is the same for making star trails, which are gorgeous astrophotographs that capture the perceived movement of the stars in the night sky.
In the case of the shot above, Fowler created the image using 800 individual shots taken 5 seconds apart. After assembling them with a star trails program called StarStaX, he added some finishing touches and tweaks in Photoshop.
