Alien World

Our world can seem alien sometimes, due to our perceptions and assumptions. Looking at things in a different way can alter how you percieve what is happening in our world.

The idea for this music video started with the almost completely cloudless skies I got on Septemper 24, 2022 in northern Esmeralda county in Nevada. While I do like some kinds of clouds in my overnight timelapses, having none at all was a treat.

Unfortunately, while this location is on the darker side of what is considered Bortle 2 skies, it is also close to a large number of airplane flight paths. Without any clouds at all, airplane and satellite streaks were showing up all over the place. It was when I was including this particular clip in this video that I reached the breaking point with airplane streaks:

For me, these flying objects are just artifical light pollution that is best removed.

When doing still night sky photography, I've found that flying objects can be removed with image stacking, which is a standard practice for lowering the noise floor in astrophotography.

However for image stacking doesn't work for timelapses, for lots of reasons.

So on October 11th 2022, I was searching around online to see if I could find any existing solutions to this problem. The best thing I could find was this video about removing birds from daytime timelapses:

While the approach suggested in the video above doesn't work for airplanes at night, it gave me an idea of what might work.

So I dug in and wrote a package called 'ntar' to remove them, the Nighttime Timelapse Airplane Remover:

While a few flying objets still slip through, showing that there is still work to be done, as of ntar version 0.1.2 the results speak for themselves:

Next I revisited the music and lyrics I had already written for this music video. The combination of daytime and night time shots of the same scene where there are no clouds at all creates the illusion of an alien world without an atmosphere that blocks the stars. I used this juxtaposition to explore our perceptions and assumptions about our reality.

The instrumentation is cello, violin, flute, piano, bass clarinet, synth bass, electric guitar, with djembe and dunun drums. I played the guitar and did the vocals.

The video is composed of six separate clips, three pairs of two each, one for the earth in the daytime, another for the sky at nighttime. Two are static timelapses, taken with Sony a7riii and Sony a7riiia bodies, each with a Sony 14mm f/1.8 lens. The moving video in the middle was taken with a Sony a9 and Sony 24mm f/1.4 lens on a Kessler Krane Second Shooter head.

That sounds great. Do you perhaps have Youtube Videos instead of Vimeo that you could link here? Vimeo doesn't let people play back the videos without an account.
