Time-lapsing is a trick of technology to get rid of our limited perception of time. By recording shots and playing them back at a different speed, one can reach to the other timescales, namely, the slow ones for time-lapses and the fast ones for slow-motion.
we currently work (as of 30 December (2013)) on time-lapsing of the Plaza Mayor from our vantage point at Mayorcita.
Our friend Carlos is also exploring time-lapsing and once in a while release some publicly. Notable are:
There are many mind-boggling timelapses of Madrid.
We work both with our Nikon D40 camera and our HTC smartphone with (http://www.lapseit.com/ LapseIt].
The D40 has no built-in feature, se we recourse to gphoto2~[1].
The following is a basic setting to capture (here every 30s):
gphoto2 --capture-image-and-download --filename "%Y-%m-%d..%H%M%S.jpg" --interval 30
To assemble the frames into a movie (15 fps):
avconv -f image2 -r 15 -i imageSequence0000%04d.jpg-vcodec libx264 output.mp4
To add the timestamp on the image itself (say at position 10x470), use this script:
#!/bin/bash timestamp=`date -r $1 +%H:%M` echo $timestamp; convert -draw "text 10,470 '$timestamp'" $1 $1.jpg
