I made a normal timelapse video a while back, but then got into HDR photography. I thought it'd be interesting to achieve the same look of an HDR photo in an entire video. So I made this.
CAMERA: Canon 5D Mark 3 [5D3]
LENSES: a 24mm f/1.4L Mk II Canon EF lens, a Sigma 12-24mm mk 2 lens, and a Sigma 14mm EF fisheye lens.
OTHER: a tripod and an intervalometer.
For a normal timelapse I would just use a cable release to lock the shutter to continuously shoot. But as each photo needed to be an HDR this meant I needed to bracket each exposure. When I held the shutter down the camera just took the bracketed number of photos and then stopped, so I needed a different method to continuously take bracketed exposures.
Rather than spending a lot of money on a fancy intervalometer I found a cheap one for £15 online that did the job. By setting the intervalometer to take 1-2 second exposures continuously *and* setting the camera to take bracketed exposures I found that the camera would take a set of bracketed exposures for every 1-2 second burst specified by the intervalometer [i.e. the intervalometer would hold the shutter down for 1 second, so the camera would take a burst of bracketed exposures during that second. I had to make sure the intervalometer exposure length allowed enough time for the camera to take all the bracketed exposures for each cycle - usually three - before it started again]. For a few of the night scenes [near the end of the video] I had to make the intervalometer hold the shutter down longer [i.e. specify a longer exposure time] to allow the camera enough time to take a burst of bracketed photos with longer exposures.
I then had a colossal set of photos for each scene to turn into individual HDR clips. I used Photomatix Pro to batch HDR merge all the photos. I then compiled all the clips together in Adobe After Effects to output the final clip. It took a ridiculous length of time to HDR merge all the photos for each clip - well over 24 hours for some of them, and I was using a fast computer [Intel i7 3770k with 32GB RAM and other frills].
Due to Vimeo's 500MB file limit for free users I had to download the version of the same video from youtube and upload that here as the file's a lot smaller. The quality's significantly reduced, but you can view the original 4k res version on youtube: youtu.be/rlruS9OcxmA
I composed a piano piece a while ago and used that to go with the video. Here it is on soundcloud:
