To avoid a blown-out sky in a sunset time-lapse, expose for the bright part of the scene, shoot RAW, and adjust exposure gradually as the light fades. Light changes fast at dusk, so a fixed setting that looks right at the opening frame will usually be wrong by the end.
Why Sunsets Blow Out
The sky near the sun is far brighter than the land below it. A camera that tries to brighten the foreground will clip the sky to white, and clipped highlights cannot be recovered. Over a clip that runs from bright daylight to deep dusk, the gap between sky and ground also shifts, so one exposure cannot serve the whole sequence.
Gear and Preparation
- A tripod that stays put for the whole run
- An intervalometer, built in or external
- A graduated neutral density filter if you want to hold back a bright sky in camera
- Fresh batteries and a card with room for several hundred RAW files
Arrive early, frame the scene, and take a few test frames while the light is still strong.
Step-by-Step Settings
- Use manual mode, RAW, and a fixed white balance such as daylight, so colors do not flicker between frames.
- Choose an aperture around f/8 to f/11 for depth, and a low ISO such as 100 to 200.
- Set exposure by checking the histogram. Keep the right edge just short of the wall so highlights stay intact.
- Turn off autofocus after focusing once, and turn off image stabilization.
- Set an interval of roughly 3 to 6 seconds for a smooth result. Shorter intervals give slower, smoother motion in the clip, while longer ones speed up clouds.
- As the light fades, lengthen the shutter speed in small steps, or lower the shutter speed gradually using exposure ramping if your camera or app offers it.
All numbers are general guidance. Adjust to the brightness and cloud movement you see.
Handling the Light Change
There are two common ways to manage the fade. Manual ramping means changing the shutter speed by a third of a stop every several minutes. Aperture priority with a locked ISO lets the camera adjust, but it can cause small jumps between frames. A popular middle route is to shoot manually and smooth any brightness steps later with a deflicker tool in editing software.
Assemble the Clip
Edit one frame in your raw editor, copy its adjustments to the rest, then export and import the frames as an image sequence at 24 or 25 frames per second. About 250 frames gives roughly ten seconds of footage.
FAQ
Should I use a filter or bracket exposures?
A graduated filter works well for a stationary camera and a straight horizon. Bracketing adds complexity in a time-lapse, so most shooters rely on careful exposure and a RAW file.
Why does my clip flicker?
Small exposure shifts between frames cause flicker. Lock white balance and aperture, avoid automatic modes, and apply deflicker in post.
The Short Version
Expose for the highlights, shoot RAW with locked white balance, and increase exposure in small steps as dusk deepens. Use a deflicker pass to smooth the rest. Treat the settings here as a baseline and watch your histogram throughout.
