An intervalometer is a crucial software for photographers that’s helpful throughout a variety of images genres and methods, together with timelapses, focus stacking, and lengthy exposures.
If you’re not accustomed to intervalometers and wish to be introduced up to the mark, you’ve come to the correct place. On this article, we are going to have a look at what an intervalometer is, discover the widespread options you’ll discover, and clarify whether or not or not it’s a software it’s possible you’ll need to add to your individual digital camera bag.

What’s an Intervalometer?
An intervalometer is a tool or a characteristic in a digital camera that may be programmed to manage the shutter launch and that enables the photographer to take a collection of pictures at a set interval. Primarily based on the wants of the operator and the necessities of the taking pictures, it may be set at common or irregular intervals of time for the taking pictures.
An interval is the size of time between frames in steady taking pictures. For instance, throughout timelapse images, between body 1 and body 2, body 2 and body 3, and so forth.
What this virtually means is that the intervalometer is programmed to open and shut the shutter at a given time over and over. This time may be set from one (1) second to hours with out the necessity to manually press the shutter button throughout the length of the taking pictures.
Mainly, intervalometers are a wise, advanced model of the timed shutter releases have been used to shoot lengthy publicity pictures within the older days of analog movie cameras.
Intervalometer Varieties
Intervalometers often are available a type of an exterior system, however in the previous couple of years, practically all digital camera producers have applied a fundamental intervalometer setting contained in the digital camera’s menu.
There are 4 fundamental varieties of intervalometers, and every of those varieties have its benefits as additionally its disadvantages.
1. Exterior (Fundamental Stage)
The commonest is the straightforward exterior intervalometer. It’s a comparatively reasonably priced system (round $20) that’s obtainable for all digital camera fashions out there.
It has a common kind just like the one proven within the product picture above, and it often takes two (2) AA batteries to function. It really works completely in virtually all conditions, besides after all underwater, and the one requirement is to pick out the one with a suitable cable connection in your digital camera. In most up-to-date fashions the cable is changeable, which means that in the event you change your digital camera mannequin later, you solely have to alter the connection cable to the corresponding one and the system will work with the brand new digital camera.
Its benefits are that it is vitally easy to function, it’s reasonably priced, and it may be used with any digital camera in virtually all of the conditions that have been talked about earlier than.
There aren’t any negatives in regards to the system itself. I’ve been utilizing any such intervalometer for greater than 15 years in virtually all-weather situations with none points.
However remember that it’s a fundamental intervalometer that lacks the options of essentially the most superior ones (extra on that later).
2. Constructed-in/Inside (Fundamental Stage)
A quite simple built-in intervalometer that has the very same options as the primary choice, though in the latest digital camera fashions, there have been some slight enhancements like the choice for publicity smoothing.
It’s a very useful gizmo that I usually use once I can’t set an exterior intervalometer as a result of lack of area on the setting, or I simply need to seize a quite simple timelapse sequence. It could possibly additionally act as a backup intervalometer in case you forgot to deliver your exterior system with you, or if the exterior system isn’t working (e.g. out of batteries).
The disadvantages of it are that it lacks extra superior options, like publicity ramping, that it drains the digital camera battery slightly quicker. And on some particular cameras, the dwell view feed is turned off, which means that you just can’t verify both the captured body or the doable adjustments in brightness ranges whereas taking pictures.
Observe: A private be aware to digital camera producers concerning the options of built-in intervalometers: I strongly imagine that it will be reasonably simple for all manufacturers so as to add these options within the inside intervalometer setting. We live within the golden period of images as all cameras obtainable right now out there have wonderful options and super optical high quality, and it’s such a disgrace to not have one thing so helpful that ultimately is barely only a piece of software program.
3. Exterior (Superior Stage)
Whenever you do skilled timelapse images and/or need to seize dynamic scenes with adjustments in publicity (e.g. a steady day-to-night and vice versa sequence) otherwise you simply need to have full management over the publicity settings at any given time, then a complicated exterior intervalometer is the correct software in your work.
With this system, you could have the power to set completely different intervals for a similar sequence. For instance, a separate interval throughout daytime and one other one for nighttime whereas checking the histogram and the publicity ranges in actual time. Some fashions have additionally the power to point out a low-resolution preview of the captured timelapse sequence on the system and the devoted distant smartphone app (verify pictures under) with out having to cease capturing.
The benefits are many for any such work, however sadly, that comes at a worth, as often these gadgets are costly ($350+) and require a studying curve with some experimentation earlier than getting the utmost potential from them.
4. Utility (Fundamental and Superior Stage)
It is very important be aware that there are some purposes for smartphones and tablets that can be utilized as intervalometers, each official and third-party apps.
Whereas a few of them are nice when it comes to options and total person expertise, most of them have points in terms of connectivity with the cameras.
Most of those purposes require a continuing (native) Wi-Fi and/or Bluetooth connection that’s susceptible to be terminated with out particular motive, so it’s important to be very cautious when utilizing a kind of apps, because the taking pictures is likely to be stopped with out noticing it.
Prior to now years, there was an enchancment when it comes to the steadiness of the connection, however take into accout as within the case of built-in intervalometers, that this may drain the digital camera battery even quicker as a result of lively connections of Wi-Fi and Bluetooth.
Key Options of Intervalometers
With an intervalometer, even on essentially the most fundamental fashions, the person will virtually at all times discover the next settings and options:
- Timer/delay begin
- Interval size set
- Publicity time set
- Variety of frames to be captured
- Externally energy
- Publicity ramping (solely on superior fashions)
When to Use an Intervalometer
An intervalometer can be utilized in quite a lot of conditions and we are going to analyze them additional right here.
1. Timelapses
The commonest use case is once we need to seize a timelapse sequence. The specified interval between every body have to be inputted to the intervalometer in addition to what number of frames we need to seize, and the intervalometer will do the remainder.
Particularly in long-term timelapse sequences (e.g. development websites or lengthy durations of time in nature), it’s important that you just use one.
2. Astrophotography
The second most typical scenario, which is similar to the primary one, is for astrophotography. For each regular nightscape pictures with the Milky Means galaxy core within the body and deep sky objects like nebulae and clusters, we at all times need to have extra knowledge to work with in post-processing, so a whole lot of similar pictures with minimal intervals between them are required that will probably be later aligned and stacked in software program.
It principally follows the identical ideas as timelapse images however with fewer complete frames.
This additionally applies to focus stacking and star path images as nicely.
3. Lengthy Exposures
One other widespread use is once we need to seize a protracted publicity shot and we need to keep away from any micro-movements on the digital camera. As an alternative of urgent the shutter button within the digital camera, having the chance of transferring it unintentionally, we use an exterior intervalometer to start out the publicity.
Additionally, in case we have to seize an publicity longer than the same old most of 30 seconds that almost all cameras have, we are able to use the maintain button on the intervalometer together with the BULB choice within the digital camera to increase the size of the publicity.
4. Distant Triggering
One other use case is for conditions when the digital camera is about within the scene however the taking pictures will begin at a later given time and the operator won’t be near the digital camera, or if we simply need to seize a self-portrait. We are able to program the intervalometer to have a delayed begin that can save priceless frames, time, and battery life.
Find out how to Use an Intervalometer
Many of the settings that will probably be analyzed listed here are widespread for each the fundamental exterior intervalometer and the built-in ones (verify the corresponding pictures).
Observe: With a purpose to higher clarify using every setting, I’ll confer with a timelapse taking pictures state of affairs on this part.
Let’s begin:
Step one to soak up case an exterior intervalometer is chosen is to be sure that it’s correctly related to the digital camera, that it has contemporary batteries, and that it’s powered on.
Observe: A number of the fundamental settings of the exterior intervalometer is likely to be written barely in a different way between producers and fashions, however ultimately, they do precisely the identical factor. Simply be certain to determine every setting earlier than taking pictures.
The primary setting to set is the size of the interval. What number of seconds, minutes, and even hours should cross between every captured body? In most intervalometers, that is famous as INTVL.
If you’re taking pictures a fast-changing surroundings, like for instance a freeway with fast-moving automobiles, a brief interval of 1-2 seconds is good.
Then the whole variety of frames to be captured have to be set. In most intervalometers, that is famous as N.
In idea, if the ultimate video will probably be rendered at 24fps or 25fps and the specified size of the clip is 10 seconds, then 240-250 frames are required.
Observe: When the three dashes are chosen, the system will shoot indefinitely till it’s manually stopped.
The final setting to be set if wanted is the delay choice, which is often famous as DELAY. This setting will decide if the taking pictures will begin straight away after urgent the Begin Button or at a later time.
Usually, once more relying on the digital camera mannequin, what’s talked about above applies to the built-in intervalometer as nicely.
Within the following pictures, we are able to see the intervalometer setting in Nikon and Fuji cameras.
Observe: In case you’re simply taking pictures a single lengthy publicity, or you’re taking pictures for a timelapse sequence with a shutter time longer than the utmost 30 seconds, there may be another choice within the intervalometer that have to be set. In most intervalometers, that is famous as LONG and on this setting the person can set the size of the publicity.
Lastly, the sound indicator setting may be set On or Off, and what it does is that in case it’s on, a “beep” tone may be heard when a setting is about and when the timer is lively. It’s helpful if you end up alone out within the area because it supplies suggestions that the timer is lively and the timelapse is being shot, however if you’re taking pictures in a closed surroundings with different individuals round, it is likely to be distracting or annoying.
Do You Want an Intervalometer?
Do you even want an intervalometer within the first place? Properly, the brief reply is: it’s as much as you.

In case you need to seize a timelapse sequence, then an intervalometer is a really essential software that can assist you could have fixed intervals between frames, letting you free to benefit from the surroundings or deal with a second digital camera that’s lively on the similar time.
The identical applies to focus stacking, astrophotography, and star path images.
Whenever you need to seize a protracted publicity, you possibly can simply set the built-in self timer of the digital camera to greater than 2 seconds — 5 or 10, for instance — to keep away from any doable micro-movements to the digital camera.
Practically all the newest digital camera fashions have added prolonged lengthy publicity lengths which might be longer than the same old 30 seconds, so you probably have a more moderen digital camera mannequin, you should utilize that characteristic as an alternative of carrying an exterior intervalometer with you.
A small be aware about movement management methods: in the event you plan to shoot a timelapse sequence with a movement management system, an intervalometer is required. The connection cable between the digital camera and the management unit additionally informs the digital camera when the movement has stopped in order to not seize any motion on the shot (move-shoot-move operate).
Nevertheless, most movement management methods have both built-in intervalometers of their management unit or a devoted smartphone app to make use of with them.
Find out how to Select the Proper Intervalometer
How do you go about choosing the proper intervalometer in your wants? My suggestion could be to first verify in case your digital camera has one built-in so that you just begin experimenting with it.
