Northern Lights Photography in Iceland: Settings and a Test-Frame Workflow
Take a test photograph, enlarge the stars, then check the aurora’s exposure. Those three steps tell you more than copying one set of settings from a different night.
Set up before the display
Choose a permitted position with stable footing and space for the tripod. Learn the return route while you can see it. Check the cloud forecast and activity before settling on a photography location; a lens cannot fix a clouded-out sky.
Use a stable tripod and a remote release or suitable camera timer to avoid moving the camera as you take the shot. Focus on a star, make a test exposure, then enlarge the image to check it. The infinity mark is a starting point, not proof of sharp focus.
The Canadian Space Agency’s photography guide explains this test-and-adjust approach. It also includes lenses with maximum apertures of f/3.5 or f/5.6; you do not have to reject a kit lens before trying it.
Start with a test exposure, then change one thing
As an example, try 6 seconds, f/2.8 and ISO 3200 if your equipment allows it. Those are settings from a photograph in Nikon’s interview with aurora photographers, not an exposure measured by Iceland.org or a promise for your sky. Review the result before continuing.
| What you see | Next check |
|---|---|
| Stars are soft | Recheck focus and camera stability. More exposure does not correct missed focus. |
| Stars look sharp but the aurora is smeared | Try a shorter exposure to record less movement. Review the brightness again afterward. |
| The green area loses detail | Inspect the RGB histogram, not only the overall brightness histogram. Shorten the exposure if a color channel is clipping. |
| The image is too dark | Try a longer exposure if movement permits, or adjust aperture or ISO. Compare successive test frames. |
Nikon’s interview specifically warns that the green channel can be overexposed even when the combined histogram looks acceptable. Find your camera’s RGB display in its manual before the outing.
Can a phone do the job?
Check whether your own model and camera app support night mode or exposure control. Practice with it before the trip and keep it stable during the capture. There is no tested phone-model ranking in this guide, and a newer model number alone does not establish what your result will look like.
Bring the equipment you know how to use. If conditions make a tripod or a prolonged stop impractical, watching without taking photographs is a reasonable choice.
Work out the timelapse before you start
At 25 frames per second, 300 photographs make a 12-second video: 300 ÷ 25 = 12. If the interval between the start of each frame is 8 seconds, those 300 frames require roughly 40 minutes of capture time. These are arithmetic examples, not a claim that the aurora will last that long.
Leave enough of each interval for the exposure and the camera’s processing. Check how your camera defines its interval and test it indoors; a setting longer than the available gap can change the capture cadence. Decide whether the resulting wait still fits your return plan.

Questions before you go
Quick answers with safety notes where it matters.
What is the best shutter speed?
There is no single setting. Shorter exposures can preserve detail in moving aurora; longer ones brighten the image but may blur its movement. Check a test frame and adjust.
Must I buy an f/2.8 lens?
No. A wider aperture can help, but the Canadian Space Agency’s guide also describes using lenses with f/3.5 and f/5.6 maximum apertures. Try your equipment before deciding to buy another lens.
How many images make a timelapse?
Divide the image count by the playback frame rate. For example, 300 images at 25 frames per second make 12 seconds of video. The time needed to capture them depends on your shooting interval.
