And now for something completely different – Vortex Start Trails
You get Matthew Vandeputte offering us a tutorial on how he created the vortex star trails sequence in his entry to the 2014 David Malin Awards (Malin is a renowned astronomer and photographer born in England who now lives and works in Australia).
As I watched his entry, I was surprised to find myself thinking “wow, the latest technology and the skill to apply it meets THE DAY THE EARTH STOOD STILL.”
And so they do.
How to Create Vortex Star Trails
Via Matthew Vandeputte:
A well known technique in astrophotography timelapse videos are Star Trails, where you ‘drag out’ rotating stars. This effect is caused by the rotation of our planet relative to the (in reality) ‘static’ stars in the night sky. Pointing your camera at the north or south star with an extended exposure will give you an effect similar to this:
One year ago, while looking at one of Lincoln Harrison’s photos, I came up with a workflow on how to achieve a spiralling or vortex effect for static timelapse sequences. The vortex star trail images are usually created using a zooming device, which zooms in during the recording of the photos, after which you stack them in post and get a spiral as the endresult.
As the timelapse community is very saturated with a lot of the same techniques, coming up with a new workflow to achieve something visually interesting is very thrilling!
