You’ve probably stumbled upon an incredible work of time-lapse where you just couldn’t get the images and the feelings out of your head. Possibly you are fascinated by nature and the slow changes that occur over a period of time. A flower blooming, a sunset or a moonrise. Maybe it was a construction project or a cityscape at night, full of activity and production. I’m a big fan of time-lapse photography and I love seeing the amazing work that people create from all over the world.
I thought I’d share a few tips I’ve learned over the years as well as touch on the basics for new and intermediate DSLR photographers who might want to try time-lapse. Since there have been some great written introductions here on DPS I decided to use a few videos and screenshots from the eBook Time-Lapse Photography: A Complete Introduction (currently 20% off) instead and focus on creating a launchpad for your experiments.
We know that time-lapse is all about the capture of change in a way that we can’t normally see. But what’s really going on in the background?
Let’s take a closer look:
What is Time-lapse Photography?
Time-lapse photography is a cinematography technique whereby the frequency at which film frames are captured (aka the frame rate) is much lower than that which will be used to play the sequence back. Put simply: We are manipulating time. Objects and events that would normally take several minutes, days, or even months can be viewed to completion in seconds having been sped up by factors of tens to millions.
The best way to get a greater feel for the power of time-lapse is to watch a few. Now I know you have seen some before, (especially if you watch reality TV) but I’m not really talking about those short clips between tribal counsel elimination decisions, it can go a little deeper if we let it. What I am talking about are the compilations that really grab your attention and make you think about the world around you. The ones that give you a better understanding about how nature changes and cities work.
It’s so much more than a gee whiz editing effect. It can be used to tell a story.
The Gear You Need To Tell Your Own Time-lapse Story:
Chances are if you’ve been shooting with a DSLR camera you probably have just about everything you need to get started in time-lapse photography. Phew!
Here are the minimum gear requirements for a new shooter.
Since a stable shooting platform of anykind is so important I wanted to include a page on tripod stability.
If you are really looking to push the limits of your creativity we’ll introduce some advanced gear to build and buy in the eBook and I wanted to be sure to include an example video a little later in this post.
Balancing Time-lapse Image Settings: Size, Quality, Space and Speed
Size, quality, space and speed; It’s nothing new if you’ve worked with digital images before but with time-lapse sequences poor planning can quickly cut a scene too short or leave you with a blinking “Card Full” message just as the sun peaks out over the mountains. There’s a lot to discuss here but if I were to boil all this down into a simple recommendation it would be this: Shoot in the highest resolution (actual image dimension) RAW format your card capacity, camera write speed and time-lapse planning will allow. RAW images will allow for non-destructive tweaking and correcting in post production (using standard or transitional editing). High resolution images will provide the freedom to crop as well as program in movement by panning, tilting or zooming into a sequence in post. Here’s a page to help you gauge the file size implications of your decision:
The Basics of Shooting Time-lapse
I can’t stress this enough: If you are new to time-lapse, review these basics then get out there and play. Your first few tests should focus more on experimenting with different changing subjects and a little less stress about creating a technically perfect rendered sequence (there’s plenty of time for that later). Get a few fun tests under your belt and the time-lapse bug is sure to carry you through to the next steps. After you’ve had a chance to survey the basics, we’ll walk through some specific scenarios and advanced topics.This section is obviously pretty big and pretty important but if I had to pull out only a few pages on the fundamentals of shooting DSLR time-lapse it would be this:
Composition, a.k.a. the art of walking around. Time to polish your crystal ball, look into the future and find interesting change and a dynamic scene.
Select a time-lapse interval to balance speed and flow.
Control your exposure to minimize and eliminate time-lapse flicker. The best way to explain this is a short video.
The most important concept here is full manual control. Now no worries if you are a little rusty on manual exposure. Take a look at this time-lapse exposure triangle as a refresher and be sure to lean on some other great DPS posts to hone in your skills.
The second most important exposure consideration is motion blur. Since our time-lapse images are played back-to-back very rapidly, the slight blurring in each individual photo blends together creating an added smoothness to the entire sequence. As a rule of thumb, try to keep your shutter speed under ~1/100th of a second. In order to get such a low shutter speed in daylight conditions we will probably need to use an ND filter (Like sunglasses for your camera, neutral density or ND filters reduce the intensity of light without altering its color).
Creating the Time-lapse
Compiling the images is where it all pays off. Creating your time-lapse movie from hundreds of still images isn’t very complicated, however approaching the rendering process without a set workflow can make things seem more complex than they actually are. I assure you once it’s built and you’ve run through it a few times you’ll be able to cruise through the time-lapse process. Here is the basic process in two nutshells: the first being the basic process.
and the second being several basic rendering software workflows.
Unfortunately I don’t have enough space in this post to launch into each workflow specifically but a quick time-lapse rendering tutorial search on Youtube/Vimeo or a glance through Chapter 5 for your specific software preference should take you the rest of the way.
Where to go from here?
You now have a firm understanding of the basics of time-lapse shooting, flicker prevention, and rendering. I encourage you to get out there and practice. Experience will be your best guide and the best way to gain experience is to test the limits of your understanding. In Chapter 6 of Time-lapse Photography: A Compete Introduction I’ve organized four challenges to test our planning, shooting, and processing skills. It is my hope these scenarios spark questions and a fascination on how these techniques can be applied to different situations.
- An Astrolapse
- The Time-lapse Holy Grail
- High Dynamic Range (HDR) Time-lapse
- We’ll also take the first step in considering how motion control devices can be used to create amazing time-lapse effects.
- Here’s another example of some of the amzing work thats been done combining advanced time-lapse motion and exposure control.
With all this information under your belt are you ready to head out and capture the changing world, or is there still a little skepticism inside that you can really create something great?
Eric Warren of Matadornetwork.com posed a related question:
Do you think time-lapse should be left to the pros?
“Pros are the guys you call when you want to put a time-lapse in your car commercial. And while we tend to put pros up on a pedestal, they are often bogged down by their clients’ needs. Most commercial advertising doesn’t push the envelope of an art form.
That job often falls to the independent artists, building their own equipment, and often not giving a rat’s ass about whether their work is going to sell. Not that I want to be too demanding here, but I want to see something mind-blowing. Either something I’ve never seen before or something familiar, shown in a new way (one thing time-lapse excels at.) ….
Consider this a call to all you independent filmmakers out there ready to push the limits of one of the most striking visual art forms.”
Take some of the stuff shared here and in the book and invest it in your next clip but also throw some of it away, do your own tests and rewrite sections how you please. Don’t let anyone tell you that you are doing things the wrong way. If you are getting the results you want then that’s all that matters. Never forget that you are the artist and it’s your story.
