The intervalometer is an essential tool for photography enthusiasts and those who wish to create time-lapse images. In this article, we explain how to use an intervalometer, the different modes, and the parameters to consider to achieve the best possible result with your camera.
What is an intervalometer?
An intervalometer is an electronic device or a built-in function in a camera that allows you to automatically trigger photo taking at regular intervals.
It is particularly useful for creating time lapses, which are accelerated video sequences showing the evolution of a subject or landscape over a long period.
How does the intervalometer work?
The intervalometer generally consists of two main elements.
The timer
This is the key first element of the intervalometer. The timer allows you to set the triggering frequency of the camera.
It can usually be set in increments of 1 second, up to several hours. In this way, you can choose how much time will pass between each shot, depending on the subject being photographed and the desired effect.
The number of triggers
The second main element of the intervalometer is the number of triggers. It determines how many photos will be taken in total during the sequence.
This parameter is important for adjusting the total duration of your time lapse, as well as for avoiding unnecessarily filling your SD card memory with superfluous images.
The settings of the intervalometer
To optimize the use of your intervalometer, it is essential to master the different settings.
The interval between shots
This parameter mainly depends on the subject you wish to photograph.
For example, for a sunset, an interval of 5 to 10 seconds may be appropriate, while for a bustling urban landscape or a natural scene with rapid movements, a shorter interval (1 to 3 seconds) will be preferable.
The duration of the sequence
The duration of the sequence also depends on the subject and the desired effect.
A time lapse of several hours or even several days can be done to show the evolution of a construction or the blooming of a plant, for example.
For more dynamic subjects, such as the movement of clouds in the sky or crowds, a shorter sequence (30 minutes to 1 hour) may suffice.

The total number of triggers
This parameter should be chosen based on the duration of the sequence and the interval between shots. Remember that each photo taken with your camera represents a certain volume of data stored on your memory card. It is therefore important to accurately estimate the number of triggers needed to cover the desired duration without saturating the memory.
Tips for successful time lapses with an intervalometer
Here are some tips to help you achieve amazing results using your intervalometer.
Choose the right shooting mode
To create a successful time lapse, it is best to use the manual mode (M) of your camera.
This method will give you full control over settings such as exposure, shutter speed, and ISO sensitivity.
This way, you can avoid unexpected variations in lighting or focus that could harm the consistency of your final video.
Consider the lighting conditions
Variations in brightness can significantly impact the rendering of your photos.
If you are doing a time lapse outdoors, be sure to adjust your settings based on the changes in light throughout the day.
You may also opt for an ND filter (neutral density filter) which will help mitigate variations in brightness and avoid unwanted blurriness.
Stabilize your camera
Using a tripod or another stabilization solution is essential to achieve sharp images and avoid vibrations when triggering the camera.
Ensure that your setup is stable and secure before starting your sequence.
Regularly check the smooth running of the sequence
Even though the intervalometer allows you to trigger shots automatically, don’t hesitate to regularly check that everything is going well during the sequence.
This will allow you to quickly detect any errors or anomalies and adjust your settings if necessary.
By following these tips and mastering the different parameters of your intervalometer, you will be able to create stunning time lapses with your camera and capture unique and original images.
