Star Trails

 

This popular effect is based on the apparent daily rotation of the stars. By combining several dozens or even hundreds of starry sky shots we can visualize the star trajectories during the photo session.

The "Star Trails" script automates loading and blending the source pictures into a composite image.

1. In the "Source" drop menu, specify which files should be loaded - all the currently opened documents (Open Files), not opened files from your computer (Selected Files), or a whole folder with images (Folder). The two latter options open a dialog for choosing the source folder or files.

2. "Fade in" option (fig. 2) adds to the trails a comet-like effect (fig. 2*).

3. To turn the "comets" in the opposite direction (fig. 3*), check "Reverse Order" gadget (fig. 3).
