What Is Time-Lapse Photography?
Time-lapse photography compresses hours of real time into seconds of video by capturing individual photos at set intervals and playing them back as a movie. A sunset that takes 45 minutes unfolds in 15 seconds. Clouds that crawl across the sky become dramatic, flowing rivers. Flowers that open imperceptibly bloom in an instant. Time-lapse reveals motion and change that are invisible to our perception of normal time. If your camera lacks a built-in intervalometer, a free online timer is a simple way to pace your shots.

Time-lapse photography is more accessible than ever. Modern cameras have built-in intervalometers, and assembly software is free or inexpensive. This guide covers the complete process: planning, camera settings, shooting technique, and post-production. Whether you want to capture a landscape transforming through golden hour or a city street pulsing with activity, these techniques will produce professional results.
How Time-Lapse Works: The Fundamentals
A time-lapse is a sequence of still photos taken at regular intervals (every 1 second, 5 seconds, 30 seconds, etc.) and compiled into a video that plays at a standard frame rate (typically 24 or 30 frames per second). The relationship between interval, frame rate, and final duration determines how your time-lapse looks:
| Shooting Interval | Playback at 24fps | 1 Minute of Real Time = | Real Time per Second of Video |
|---|---|---|---|
| 1 second | 24 photos = 1 sec video | 2.5 sec video | 24 seconds |
| 3 seconds | 24 photos = 1 sec video | 0.83 sec video | 72 seconds (1.2 min) |
| 5 seconds | 24 photos = 1 sec video | 0.5 sec video | 2 minutes |
| 10 seconds | 24 photos = 1 sec video | 0.25 sec video | 4 minutes |
| 30 seconds | 24 photos = 1 sec video | 0.08 sec video | 12 minutes |
Choosing Your Interval
The interval depends on how fast the action moves and how you want it to appear:
- 1 to 2 seconds: Fast-moving subjects: people walking, traffic, crowds. Produces smooth motion.
- 3 to 5 seconds: Clouds, shadows moving across a landscape, moderate-speed subjects. The most commonly used interval.
- 5 to 10 seconds: Slow-moving clouds, sunrise/sunset light changes, construction progress.
- 10 to 30 seconds: Very slow changes: stars moving, flowers opening (use shorter for visible rotation), fog rolling in.
- 30 to 60 seconds: Extremely slow changes: star trails building, very slow cloud formation.
- Minutes to hours: Construction projects, plant growth, ice melting. These “holy grail” time-lapses span hours, days, or months.
How Many Frames Do You Need?
To calculate the number of frames needed:
Frames = desired video duration (seconds) x frame rate (fps)
For a 10-second time-lapse at 24fps: 10 x 24 = 240 frames. At a 5-second interval, that takes 240 x 5 = 1,200 seconds = 20 minutes of shooting time.
A good rule of thumb: plan for at least 240 to 360 frames (10 to 15 seconds of final video) for any time-lapse. Shorter time-lapses feel rushed. Longer is always better since you can trim in editing.
Camera Settings for Time-Lapse
| Setting | Value | Why |
|---|---|---|
| Mode | Manual (M) | Consistent exposure across all frames prevents flicker |
| Aperture | Fixed (f/5.6 – f/11 for landscapes; varies by subject) | Consistent depth of field; avoid “aperture flicker” (see below) |
| Shutter Speed | Fixed (should be shorter than interval) | Must complete before next frame is due |
| ISO | Fixed (as low as possible) | Consistent noise level; prevents exposure flicker |
| White Balance | Fixed Kelvin or specific preset | Auto WB shifts between frames, causing color flicker |
| Focus | Manual (set once, do not touch) | Autofocus may refocus between frames, causing “focus breathing” |
| Image Stabilization | OFF | IS corrections between frames cause frame jitter |
| File Format | RAW (for maximum post-processing) or JPEG (for simpler workflow) | RAW gives the most flexibility but creates large files |
The Golden Rule: Everything Fixed
The most important principle of time-lapse photography is consistency. Every frame must have the same exposure, white balance, and focus. Any variation between frames creates visible flicker or jumping in the final video. This means:
- Manual exposure: Never use Auto, Aperture Priority, or Shutter Priority. Auto modes adjust between frames based on small changes in the scene, creating exposure flicker.
- Manual white balance: Auto White Balance shifts color temperature between frames. Set a fixed Kelvin value or use a preset (Daylight, Cloudy, etc.).
- Manual focus: Switch to manual focus after achieving your desired focus point. Autofocus may hunt between frames.
- Image stabilization off: Stabilization makes micro-corrections between frames, causing the video to jitter.
Aperture Flicker
Even in Manual mode, some cameras produce slight exposure variation between frames. This is called “aperture flicker” and it happens because the aperture blades do not close to exactly the same position every time. To minimize this:
- Shoot at the lens’s widest aperture (where the blades are fully open and there is no variation).
- If you need a smaller aperture, some photographers tape the aperture ring or use a manual lens where the aperture stays mechanically fixed.
- Deflicker the sequence in post-processing using dedicated software (LRTimelapse, Adobe Premiere’s deflicker tools).
Shutter Speed and Motion Blur
Shutter speed in time-lapse affects the appearance of motion within each frame. Fast shutter speeds (1/500s) freeze all motion, creating a staccato, stuttery look in the final video. Slower shutter speeds (1/4s to 1 second) blur moving elements within each frame, creating smoother, more cinematic motion in the video.
The “180-degree shutter rule” from cinema suggests using a shutter speed roughly half the interval. If your interval is 4 seconds, use a 2-second exposure. If your interval is 2 seconds, use a 1-second exposure. This produces natural-looking motion blur.
Achieving slow shutter speeds in daylight requires an ND filter. A 3-stop to 6-stop ND filter lets you use slower shutter speeds even in bright conditions, producing that smooth, cinematic motion blur that makes professional time-lapses look polished.
Essential Equipment
Tripod
A rock-solid tripod is essential. The camera must not move at all during the entire time-lapse sequence (which may last 30 minutes to several hours). Even a tiny shift between frames creates visible jitter in the video. Use a heavy, stable tripod. If it is windy, hang weight from the center column hook. On soft ground, let the tripod settle for a few minutes before starting.
Intervalometer
An intervalometer (either built into the camera or an external accessory) triggers the shutter at precise intervals. Many modern cameras have built-in interval timers in the menu. External intervalometers offer more features: programmable intervals, total frame counts, and long-exposure timers for Bulb mode sequences.
Extra Batteries and Memory Cards
A 2-hour time-lapse at 5-second intervals is 1,440 frames. In RAW format, that could be 30 to 50 GB of data. Bring extra memory cards. Battery life varies, but a single battery rarely lasts for a multi-hour sequence. Bring fully charged spares and swap quickly between intervals if needed (the camera pauses for a moment during the swap).
ND Filters for Motion Blur
To achieve the cinematic motion blur described above, you need slow shutter speeds even in daylight. A 3-stop to 6-stop ND filter darkens the scene enough to use shutter speeds of 1/4s to 2 seconds in bright conditions. Variable ND filters are convenient but can introduce uneven exposure at extreme settings.
Shooting Specific Time-Lapse Subjects
Clouds and Sky
| Parameter | Value |
|---|---|
| Interval | 3 – 5 seconds |
| Duration | 30 – 60 minutes (for 10 – 20 seconds of video) |
| Aperture | f/8 – f/11 |
| ISO | 100 |
| Shutter | 1/4s – 1s with ND filter for smooth motion; 1/500s without for crisp frames |
Clouds are the classic time-lapse subject. They move fast enough to create compelling motion at standard intervals. Include landscape elements in the foreground (mountains, buildings, trees) to anchor the scene and provide a static reference against the moving sky. The best cloud time-lapses have dramatic, fast-moving weather: storm fronts, rolling cumulus, or fog creeping through valleys.
Sunrise and Sunset
| Parameter | Value |
|---|---|
| Interval | 5 – 10 seconds |
| Duration | 45 – 90 minutes (the full color transition) |
| Challenge | Light changes dramatically; exposure must be managed |
Sunrise and sunset time-lapses are spectacular but technically challenging because the light changes by several stops over the course of the sequence. In full Manual mode, you will need to gradually adjust exposure (ISO or shutter speed) as the light changes. Alternatively, use Aperture Priority with a fixed aperture and Auto ISO, then deflicker the sequence in post. Advanced time-lapse software (LRTimelapse) handles this exposure ramping smoothly.
City Traffic and People
| Parameter | Value |
|---|---|
| Interval | 1 – 3 seconds |
| Duration | 20 – 60 minutes |
| Aperture | f/5.6 – f/8 |
| Shutter | 1/2s – 1s for smooth traffic flow; 1/500s for staccato movement |
Urban time-lapses work best with shorter intervals (1 to 3 seconds) to capture the fast pace of city life. Motion blur from slower shutter speeds makes traffic and pedestrians flow smoothly. Compose from elevated positions (rooftops, bridges, parking garages) for the most dynamic overhead perspectives of moving traffic.
Stars and the Night Sky
| Parameter | Value |
|---|---|
| Interval | Equal to exposure time + 1 second (e.g., 25 seconds exposure, 26 second interval) |
| Duration | 2 – 6 hours |
| Aperture | f/1.4 – f/2.8 |
| Shutter | 15 – 25 seconds (per 500 Rule from your star photography guide) |
| ISO | 1600 – 6400 |
Star time-lapses show the rotation of the night sky, with the Milky Way arching across the heavens. Shoot from a dark sky location. Keep the interval just slightly longer than the exposure time to minimize gaps. The resulting video shows stars streaming across the sky while the landscape remains static, which is a mesmerizing effect.
The Holy Grail: Day-to-Night Transitions
The “holy grail” of time-lapse photography is capturing the transition from day to night (or night to day) in a single continuous sequence. This is technically challenging because the light changes by 10+ stops over the course of 30 to 60 minutes.
Approaches
- Aperture Priority with deflicker: Set a fixed aperture and let the camera adjust shutter speed (or ISO). The resulting frames will have slight exposure jumps, but deflicker software smooths these in post. This is the simplest approach.
- Manual ramping: Gradually adjust shutter speed (and eventually ISO) by hand throughout the transition. Requires constant attention and produces the smoothest raw results but is labor-intensive.
- Automated ramping: External intervalometers (LRTimelapse with Promote Control, or similar systems) automatically adjust exposure during the sequence based on a programmed ramp or real-time light metering. This produces the best results with the least manual effort.
Assembling Your Time-Lapse
Software Options
- LRTimelapse + Lightroom: The gold standard for time-lapse post-processing. Edit keyframes in Lightroom, and LRTimelapse smoothly interpolates edits across all frames. Handles deflicker, exposure ramping, and color grading. Paid software with a free trial.
- Adobe Premiere Pro / After Effects: Import image sequences directly. Good for assembly, stabilization, and output. Built-in deflicker in Premiere.
- DaVinci Resolve: Free, professional-grade video editor that handles image sequences. Excellent color grading tools.
- FFmpeg: Free command-line tool that converts image sequences to video. No editing, but fast and efficient for simple assembly.
Output Settings
For the highest quality output:
- Resolution: 4K (3840×2160) is the current standard. If your camera captures more pixels, shoot at full resolution and downscale to 4K in post for even sharper results.
- Frame rate: 24fps for a cinematic look, 30fps for a smoother broadcast look.
- Codec: H.264 for web sharing, ProRes or H.265 for maximum quality.
Adding Motion: Sliders and Pan/Tilt Heads
A static time-lapse plays from a fixed camera position. Adding subtle camera movement, a slow pan, a gentle tilt, or a linear slide, transforms a good time-lapse into a cinematic one. Motion adds depth, reveals the scene progressively, and keeps the viewer engaged.
Motorized Sliders
A motorized slider moves the camera along a rail over the course of the time-lapse. Over 30 minutes, the camera might slide 2 to 3 feet, creating a subtle parallax effect that adds a sense of depth. The movement should be slow enough that it is barely perceptible frame to frame but obvious when played at speed.
Motorized Pan/Tilt Heads
A motorized pan/tilt head rotates the camera slowly during the sequence. A 10 to 30 degree pan over 30 minutes is subtle in the final video but adds significant production value. Many heads can be programmed for specific movement curves.
Digital Motion in Post
If you do not have motorized hardware, you can simulate camera motion in post-processing. Shoot at full resolution (or even wider than needed), then slowly pan/zoom the crop window across the image during assembly. This is not as smooth as real camera motion but is free and surprisingly effective.
Common Time-Lapse Mistakes
1. Using Auto Exposure
Auto exposure adjusts between frames, creating visible “flicker” (brightness pulsing) in the final video. Always use Manual mode with fixed ISO, aperture, and shutter speed. The only exception is holy grail day-to-night transitions, where controlled exposure ramping is necessary.
2. Using Auto White Balance
Auto White Balance shifts color temperature between frames, creating a color “pulse” in the video. Set a fixed Kelvin temperature or a named preset (Daylight, Cloudy, Shade).
3. Not Shooting Enough Frames
A 5-second time-lapse feels incomplete. Plan for at least 10 to 15 seconds of final video (240 to 360 frames at 24fps). For important scenes, shoot longer than you think you need. You can always trim, but you cannot add frames you did not capture.
4. Bumping the Tripod
Any movement of the camera during the sequence creates a visible jump in the video. Set up the tripod carefully, let it settle, and then do not touch it for the entire duration. Route cables and straps so they cannot catch wind and pull the camera.
5. Running Out of Battery or Storage
There is nothing worse than a stunning 45-minute sequence that stops at minute 30 because the battery died or the card filled up. Always start with a full battery and an empty card. Calculate the storage needed before starting (frames x file size).
6. No Motion Blur (Staccato Look)
Fast shutter speeds in time-lapse create a harsh, stuttery playback where each frame is frozen. This looks unnatural and distracting. Use slower shutter speeds (with an ND filter if needed) to add motion blur within each frame, producing a smoother, more cinematic final video.
Frequently Asked Questions
How long does it take to shoot a time-lapse?
It depends on the subject and desired video length. A 10-second video at 24fps needs 240 frames. At a 5-second interval, that is 20 minutes of shooting. At a 10-second interval, that is 40 minutes. Star time-lapses typically require 2 to 4 hours. Plan for longer than you think you need.
Should I shoot RAW or JPEG for time-lapse?
RAW gives you maximum post-processing flexibility (critical for day-to-night transitions and color grading), but creates very large file sets (30+ GB for a long sequence). JPEG is smaller and faster to process but limits your editing options. For important projects, shoot RAW. For casual or high-volume time-lapse work, quality JPEG is acceptable.
Can I make a time-lapse with my phone?
Yes. Most modern phones have a built-in time-lapse mode that handles interval, assembly, and output automatically. The results are good for social media sharing. For professional quality, a dedicated camera gives you more control over exposure, white balance, resolution, and motion blur.
What is a hyperlapse?
A hyperlapse is a time-lapse where the camera moves a significant distance between frames (not just the small slide of a motorized slider, but walking or driving between positions). The resulting video shows dramatic movement through a scene over time. Hyperlapses require careful stabilization in post-processing because hand-positioned frames are never perfectly aligned.
How do I handle changing light conditions?
For gradual light changes (sunrise/sunset), use Aperture Priority mode with a fixed aperture and deflicker the sequence in post. For the best results, use LRTimelapse or similar software that smoothly ramps exposure across keyframes. For sudden light changes (clouds passing over the sun), Manual mode will cause over/under-exposure, but these transitions can look dramatic and natural in the final video.
Try This: Practice Exercises
Exercise 1: Your First Cloud Time-Lapse
On a day with moving clouds, set up your camera on a tripod pointing at the sky with some landscape in the foreground. Settings: f/8, ISO 100, 1/500s, 5-second interval. Shoot for 30 minutes (360 frames). Assemble the frames into a video at 24fps using any video editor. You will have a 15-second time-lapse showing clouds streaming across the sky. This first success teaches you the entire workflow from capture to final video.
Exercise 2: Motion Blur Comparison
Shoot two identical time-lapses of a busy street, side by side. One at 1/500s (frozen traffic), one at 1/2s with an ND filter (blurred traffic). Assemble both at 24fps and play them back-to-back. The difference in perceived smoothness is dramatic and demonstrates why motion blur matters in time-lapse.
Exercise 3: Golden Hour Light Change
Set up 30 minutes before sunset facing west with a scenic foreground. Use Manual mode: f/8, ISO 100, and a shutter speed that properly exposes the scene. Shoot at 5-second intervals. As the light dims, you will need to gradually lengthen the shutter speed (or raise ISO) to maintain exposure. Check every 5 minutes and adjust. This exercise teaches you the exposure ramping challenge and prepares you for the holy grail day-to-night technique.
