Since the 2013 road trip I managed to compile and fill in most of gaps in this project – the project I’ve been working on intermittently for 3 years. It’s a time lapse I had started in 2010 when I was caught and shocked by the realism presented by time lapse photography. Those pioneers on Youtube and Vimeo made nature time lapse videos with moving clouds and starry night.
I made a rough calculation and I immediately realized how fast the shutter life will be consumed should I use a DSLR. A 1000 exposures for one time lapse at a interval of 6 seconds. So I started with bridge camera, but this time the image quality and lagging speed greatly reduced the success rate. Finally to only have one camera to work with during travel I started serious time lapse photography. The first series was shot in UK during my internship and I was first amazed by how transient but colorful the nature could be.
Gradually problems began to appear, the flickering issue posed a challenge to correct. Then comes the annoying vibration. Sometimes caused by winds, others by necessary manual control interruption. When more videos were taken between sunrise and set, the exposure control became a serious hurdle to smooth the transit. And worst of all, my physical perseverance to withstand the winds and bitter coldness for one hour.
In 2011 the music was chosen and I start to fill in each melody with the appropriate clip. The flicker was vastly reduced with VirtualDub filter. When better clips were available, the entire edition would be moved around and discarded. In 2012 I got my new D7000, the new feature avtive D-lighting was both the curse and bless of photography. On one side it could greatly expand dynamic range for single shot JPEG, on the bad side it introduces extreme flicker between images due to its algorithm treats images individually. People moving around was suppressed with statistics filter with my coding effort. Every times when new semester started it became another down time for me to doubt if I could eventually finish this project.
At the end of 2013 I traveled to the Big Bend National Park in Texas for the final shot. Against all odds, I managed to reduce the light from cars moving by and finished this project. Please enjoy the video. For best effect, use full screen, dim lights and sounds up! If you like it, help me share it so others would view as well.
Time lapses were mostly taken at 6 seconds interval. To reduce data burden, most were taken at medium resolution. The preprocessing were done at 4K resolution if applicable.
