Cascada de Nubes en La Palma

On our hike to Pico Birigoyo I had the chance to record this time-lapse video of a spectacular phenomenon – the “falling clouds”. This “Cascada de Nubes” is quite typical for La Palma. When the weather conditions are right the build-up clouds from the east side of the ridge are pressed across the so called “Cumbre Nueva”. The clouds flows over the edge and fall like a waterfall until they mysteriously disappear.

The time-lapse has been recorded with a Fujifilm X-T1 camera. The post-processing has been done with blender.

A sea of clouds – short time-lapse from Pico Nambroque on La Palma

On a hike to Pico Nambroque on La Palma I had the chance to record a short time-lapse which shows the movement of the clouds over the island. I used a Fujifilm X-T1.

As usual, the exposure time, ISO value and focus were set to manual, the white balance was set to 7100K and the frames were recorded in the RAW format. The frames were then post-processed using I did the deflickering using the following script:

Day and Night on La Palma – The highlights from my last La Palma holiday

On my last La Palma holiday I did lots of experiments with my X-T1 camera. This time I was especially looking into time-lapsing. The result is “Day and Night on La Palma” – a 5 minute video about this beautiful island. To me, La Palma is the perfect place for doing this kind of videos. In this short video I want to show the highlights of my last holiday. Lots of stars, clouds and sunsets… 🙂 In order to make this video I visited many different places of the island. Some of them were Roque de Los Muchachos, Mirador del Jable, Mirador del Time and Pico Birigoyo. The music title “Worlds” has been composed by Jacob Tyler. I found it on I hope you enjoy the video 🙂

For those who are interested in technical details: Most of the time-lapse recordings have been taken with the Fujifilm X-T1. My self-made 12V power adaptor was sometimes quite helpful. On the camera everything was set to manual (despite a few recordings with aperture priority).

The whole time-lapse post-processing I did on Linux (parts of this tutorial I found very useful). First, I developed the RAW images from the camera using the open source tool rawtherapee. In order to reduce flickering I used this deflickering script developed by Vangelis Tasoulas to reduce the flickering. In case the recorded time-lapse was too short, I used the free open source tool slowmoVideo (developed by Simon A. Eugster) to interpolate additional frames. Finally, I used kdenlive for creating and cutting the videos. Previously I used openshot but at this point in time kdenlive seems to be more stable.

One remark regarding the Fujifilm X-T1 and time-lapse recording: Sometimes I had problems with the X-T1 when the time between the frames was too short (< 3s). It introduced random delays of up to several seconds so that the images taken were not recorded at the same interval. This resulted in videos which did not play smooth. Increasing the time between the frames resolved this problem. Probably the camera did not finish writing the previous image to the SD card. After some research I found that this is probably a fragmentation problem of the SD card. Using high quality SD cards and formatting the card prior to its usage should help in the future.

Milkyway time-lapse with Vixen Polarie & Fujifilm X-T1

This article is about creating a time-lapse with the Vixen Polarie and a Fujifilm X-T1 camera. Tonight I did a first experiment with the Vixen Polarie. I did not know this device before. It was rent to me by a friend on La Palma. Basically it is a kind of motorized mini-mount for the camera. One the one and can track the night sky (compensate the earth rotation) for longtime exposures. This just needs a good alignment to Polaris. On the other hand one can just mount the camera in order to do time lapse recordings.

I decided for the second option and tried to make my first time lapse with the Vixen Polarie and my Fujifilm X-T1 of the milky way. Below is the result. I am quite pleased with the smooth movement from left to right. Probably something similar could also be achieved by using a good video cut software. However, doing it this way I always have the full resolution available and the post processing is simpler.
