Instagram isn't the perfect place for viewing a video. So Ive uploaded the video to youtube.
I might add, I had trouble with rain droplets getting on the lens (used an ndx400 filter). So I would wipe them off between frames. Unfortunately I didnt get all of the droplets and had to edit them out in post production.
I think the tripod moved at some stage too, so you might see the image budge during the video.
I also made the mistake of changing the shutter speed twice. Never again! It made post production so much more time consuming, trying to match/blend the exposures.
