MSR tent stars
Several of you have asked us what miracle we managed to lay night shots like those we have posted on our Facebook page. Based on this observation, it m & rsquo; appeared consistent to write this small article, which should enlighten you on the subject.

One of the first prerequisites, which is as common to the picture that & rsquo; in timelapse, is to choose the & rsquo; location and timing. According to the criteria of & rsquo; Hello World Bike, the requirements are as follows :

  • No light pollution (city, routes, etc…)
  • A time certainly cleared (no clouds or haze)
  • An air cleared, which ensures maximum visibility
  • In the case of & rsquo; d & rsquo a presence; a lake, minimum wind to enjoy d & rsquo; a beautiful reflection
  • No moon
  • A sacred dose of motivation for s & rsquo; root out of the tent in the cold



So often it is customary to consider it n & rsquo; is the & rsquo; camera but the photographer who makes a good photo, there is in the case of night shots minimal hardware requirements. A smartphone will not know how to answer that kind of perilous scene, due to the small size of its sensor.

In our opinion, so you have to provide yourself with d & rsquo; a device with d & rsquo; at least one sensor″ and d & rsquo; one the brightest possible optical. In our case, l & rsquo; apparatus behind these pictures is a Fujifilm XT2 (APS-C) with d & rsquo; a 12mm f2.0 lens fixed. The wide angle is ideal for a scene like “camp under the Milky Way”.


Camera settings

The issue of & rsquo; a night photography is having to work with extremely low light. To capture a sufficient amount of light, applicable d & rsquo; use a maximum aperture, but also to choose a time & rsquo; sufficiently long exposure. Not too long either, the risk that the stars “stretch” (and yes, the earth has a tendency to turn on itself, did & rsquo; forget !). The magic formula to determine the time d & rsquo; maximum exposure before seeing the stars deform as follows :

d & rsquo time; maximum exposure : 500/(equivalent focal)

In our case, a focal length of 12mm gives us an equivalent of full sized 18mm, due to its 1.5x crop factor. So, time d & rsquo; maximum exposure would be 27 seconds.

On setting ISOs, it is based on other parameters (opening, time & rsquo; exposure) and must be adjusted to obtain a sufficiently bright picture. The lower value is the best, to limit noise. For our Photo, a value of 3200 ISO was enough.

To & rsquo; get image sharp, we can only recommend d & rsquo; s the self-timer & rsquo; sure not to move at the outbreak of the & rsquo; shutter.


To & rsquo; get a picture a little more personal that & rsquo; a simple Milky Way, we recommend & rsquo; add the tent to your composition & rsquo; Image. Some tips for successful integration :

Do not keep your lights headlamp for the duration of the & rsquo; exhibition, the tent appear completely exploded. For a photo 15 seconds, it n & rsquo; is not necessary & rsquo; light the lamp more & rsquo; one second (according to the power of & rsquo; lighting).

To & rsquo; achieve homogeneity over the entire surface of the canvas, scan all the walls with your lamp (in less than & rsquo; one second, c & rsquo; is sporty !). So, the tent will appear in its most beautiful form, with the right exposure.

Another solution is d & rsquo; use an extremely small light source, as pictured below :


Right here, a small candle was placed on the middle of the truck, thereby making this hot, warm light while n & rsquo; not bright colors thanks to its low light.


The first technique of & rsquo; on-off of the front of a second can not s & rsquo; applying to a timelapse, unless you really want to spend the night at his lamp switcher. It is therefore necessary to cover his lamp d & rsquo; a fabric order & rsquo; get weakened lighting. Test multiple up & rsquo locations; to obtain & rsquo; more diffuse lighting solutions.

Once you are satisfied with your photo, you can start your interval timer for the night and see the result tomorrow:

A final detail can cause you a nasty surprise upon waking : the duration of the battery.


While most reflex cameras widely held battery level road, d & rsquo; others can not stand all night without stopping by shooting. D & rsquo; other, cameras may not necessarily be charged with operating, it is necessary to turn off the power to recharge the battery (especially via USB). So, how to do ?

Once again, Hello Bike World is there for you ! That's our trick (the figures depend on your model & rsquo; unit) :

  1. Connect your device to an external battery, you carefully cling to your tripod.
  2. Select Sleep programmed 45 seconds after tripping.
  3. Choose an interval of & rsquo; one minute (minimum) between each photo for your timelapse.
  4. Let the magic happen !

explanations: By choosing a larger interval than the time standby, l & rsquo; device will have time to s & rsquo; off between each shot. Once the & rsquo; camera in standby, recharge s & rsquo; operates, up & rsquo; that the & rsquo; standby unit so, in the & rsquo; case 15 Seconds later. This cycle is more than enough to keep the battery has a stable level of charge, and thus to hold the full night, despite the 600 clichés request a timelapse 20 seconds.


retouching software

After importing your photo on your computer, free your creativity to bring out the stars or your subject (ex: try) according to your preferences. In our case, an increase in the brightness of the sky and that & rsquo; a slight touch of color helped make more & rsquo; glow photo.



There you go ! C & rsquo; is (almost) that simple ! You now have the technical tools, you shine with a composition of & rsquo; original and poetic image !



engineer 26, I am not only passionate about watts and technology. Writing, music, travel and sushi are among the things that speak to me, among others.
