If you’d like to make an easy, and indeed logical, transition from shooting stills to shooting video, time-lapse photography is the best way to do it. Not only is time-lapse photography based on still images, the technique shows the passing of time in such an interesting way that even mundane scenes can be brought to life and made to look magnificent.
So, what is time-lapse photography? In a nutshell, it’s a movie that’s made up of a sequence of still images that show the passage of time. This could be minutes, hours, days or even weeks.
To shoot a time-lapse you need to attach a camera to a tripod so it’s fully supported and can’t move. You then, using either an in-camera intervalometer or one built into a shutter remote, set frequency – how often an image will be taken, the total number of frames to be taken, and on some in-camera intervalometers you can even set a start time so the time-lapse could start shooting when you’re asleep for instance.

The period of time between each shot taken will always depend on how fast or slow elements in the scene are moving. If there’s little wind and cloud movement is minimal, you may want to set an interval of one shot every 30 seconds. Whereas if there’s a lot of movement it may be every five seconds or less.
The advantage of the latter is that you’ll shoot more frames in a shorter space of time, but if there’s little movement the longer interval means you’ll capture more movement from one shot to the next. Getting a feel for the exact interval time in different situations all comes down to practice, so if you’d like to get it right first time do some test shoots where you shoot enough images for 10 seconds of footage to see how different intervals look.
Total number of shots
Shooting time-lapse photography is time-consuming and you have to set enough time aside to be able to shoot the images you need to then create a movie that plays at the standard 24fps. The total number of images you’ll need to shoot ultimately depends on how long you want your time-lapse to be.
Basically, for every one second you need 24 frames, so simply multiply the number of seconds required by 24. For a 30 second time-lapse you’d need to shoot 720 images, and if the camera was set up to take a shot every five seconds that would take an hour to shoot. If you were shooting at a 30-second interval it would take an eye-watering six-hours to shoot the required number of images. Some scenes need it, so if this is the case make sure you have a chair, a good book and a flask of tea!
Manual vs aperture priority
There are two main options for shooting mode when shooting a time-lapse. The first is to put the camera into manual mode so that exposure is fixed and any brightening or darkening of the scene will be picked up. An advanced version of this is where you shoot a day to night scene and make minor adjustments to shutter speed and ISO as the scene gradually darkens.
The second, and easier, option is to shoot in aperture priority mode. This is the mode where you set ISO and aperture, and the camera sets the appropriate shutter speed for a correct exposure.
When shooting in this mode you’ll need to set the necessary amount of exposure compensation if required. One of the problems with aperture priority is that if there are flashing lights or quick changes in brightness between one shot to the next, the camera will be fooled into under and overexposure which will ultimately result in flicker.
Flicker is when the brightness of frames is slightly different so that when the time-lapse is played back as a video you see a flicker. More advanced software can remove this, but there’s also another way of reducing this problem and it all comes down to the lens you use.

The kit you’ll need
The great thing about time-lapse photography is that it can be as simple or complicated as you like, so at the basic end there’s very little you actually need beyond a camera, kit lens and tripod. And if your camera has a built-in intervalometer you won’t even need a shutter remote with one built in.
We’ve already discussed flicker, and one of the other causes of flicker is autofocus lenses. The problem here is that each time the aperture stops down to take a shot, the exact amount it closes down to is imperceptibly different each time, which makes no difference when shooting generally. But when shooting a sequence of images for time-lapse, that difference becomes noticeable as flicker because of the ever so slight variation in exposure.
The most effective way to combat the problem is to shoot with a manual lens. This may be an old lens made by the manufacturer of your camera or a modern third-party option from the likes of Samyang or Tokina. With these lenses, you will, of course, have to focus manually, but the fact that the aperture is set manually and is separate from the camera means that it’s fixed in one position and won’t cause flicker.
If you have filters such as a polariser and ND grads make sure you use them to control exposure and to shoot the best images possible. If you don’t have grads you could underexpose shots by one or two stops and recover the foreground in post, but filters will always be the better option because they will allow you to maintain optimum image quality.

Software and processing
Shooting a time-lapse is only half of the process. Once you have all of your stills you’ll need special software to piece them together into a movie. There are both free versions and fully featured paid options that are used by the professionals, so you can decide what works best for you. We’ll take a look at three options in a moment.
Free for Mac – Time-lapse Assembler (opens in new tab)
Arguably the best free Time-lapse software available, Time-lapse Assembler is unbelievably easy to use. Unfortunately, it’s only available for Mac so if you’re a Windows user you’ll have to look at a different option if you wish to use free time-lapse software.
Free for PC – Startrails.de (opens in new tab)
As the name suggests Startrails.de is actually software designed for creating star trail images, but it also allows you to create a basic time-lapse. It’s easy to use and considered one of the best options for creating star trails on a PC, so a double bonus if you shoot this type of photography.
Fully featured pro option for Mac & PC - LR Timelapse (opens in new tab)
This software is one of the best options available and works as a Lightroom plugin. It offers a wide variety of features not available with Startrails.de and Time-lapse Assembler, and the free version of LR Timelapse allows you to make a time-lapse comprising up to 400 still images.
