Here is another video from the series of videos I am taking to cover different parts of Luxembourg in order to make a full time-lapse composition afterwards. 
(Better watch it in full HD.)





Technical info:



  • Aperture priority mode, f-2.8
  • Nikon D7100 + Nikkor 24-70 f2.8
  • ISO 100

  • 500 pictures taken

Self-Criticism:

  • I should have stayed a bit longer at night to cover a longer duration. 
  • There are still some flickering remaining due to the change of the shutter speed. Note that the last frame of this video was taken at 8'' shutter speed.

Noertzange train station

I started a new time-lapse project about Luxembourg. I will be basically shooting many time-lapse videos these two months, and at the end, I will create a big composition containing everything. Here is the video:
(Better watch it in full HD.)




Technical info:

  • Nikon D7100 + Nikkor 24-70 f2.8
  • Aperture priority mode: f-2.8
  • ISO 800
  • 360 pictures taken 
  • Total duration: 1h 30 min.
  • Interval: 15 seconds. 
  • Speed-up factor: x360.

Self-criticism: 

  • I forgot to put the white balance in the manual mode, but it's not a big problem.
  • 15 seconds are good for the clouds, but not enough for the trains passing. I should have done a smaller interval (10 seconds maybe). 
  • The moon at the end is perfect, I didn't check the position of the moon beforehand, but it was out of complete luck :)

Image reconstruction using genetic algorithm



In this video, a genetic algorithm is running to evolve the image (on right) which consists of 50 triangles. The algorithm determines the position, the size and the color of each triangle each time, than the whole image is evaluated and the difference with the original one (on left) is plotted on the graph.
