Hidden inside the Photos app is a feature most iPhone owners never find: you can turn any Live Photo into a long exposure. No extra app, no tripod, no settings. A waterfall you shot last summer can become silky smooth with two taps.
This guide walks through exactly how to do it, then covers the limits honestly, because the feature is genuinely useful but it stops short in some specific, predictable ways. Knowing where the ceiling is will save you a frustrating evening of wondering why your shots don't look like the ones online.
What a Live Photo Actually Is
When Live Photo is on (the circular icon in the Camera app), your iPhone records a short clip of video around the moment you press the shutter, not just a single still. Apple has shipped this since the iPhone 6s.
That little clip is the raw material for the long exposure effect. The Photos app takes the frames from the clip and blends them into one image, so anything that moved during those moments smears into a blur while static elements stay sharp. It's the same core idea behind dedicated frame-stacking apps, just smaller and fully automatic.
How to Turn a Live Photo into a Long Exposure
- Shoot a Live Photo. Open the Camera app and make sure the Live Photo icon (the concentric circles at the top) is on. Photograph something with motion: a stream, traffic, a fountain, waves.
- Hold still while shooting. The effect blends frames from before and after your tap, so keep the phone as steady as you can for the whole moment, not just the instant you press the shutter.
- Open the photo in the Photos app.
- Tap the Live menu in the top-left corner of the photo.
- Choose Long Exposure.
Photos rebuilds the image with motion blur applied. You can switch back to the normal Live Photo at any time from the same menu, so the conversion is never destructive.
Good first subjects: waterfalls and fountains (water turns silky), nighttime traffic (headlights stretch into streaks), and crowds (people blur into ghosts while the scene stays sharp).
The Limits of the Live Photo Method
Here's where the built-in trick runs out of road. None of these are bugs; they're just the boundaries of a convenience feature.
1. You get about 3 seconds, period
A Live Photo only captures around 3 seconds of footage, so that's the most motion the effect can ever blend. For a fast waterfall, 3 seconds might be enough. For slow-moving clouds, calm water you want fully flattened, or anything like star trails (which need exposures measured in minutes, not seconds), it simply cannot get there. There is no setting to extend it.
2. No control over anything
You can't choose how the frames blend, can't adjust ISO, can't set focus manually, and can't decide when the exposure starts or stops. The effect is applied after the fact to whatever the Live Photo happened to capture. If the result looks wrong, your only option is to reshoot and hope. There's also no preview while shooting; you find out what the long exposure looks like only after converting it in Photos.
3. No RAW output
The converted image is a standard compressed photo. There's no RAW file, which means very little latitude for recovering blown highlights or lifting shadows in an editor. Night scenes and high-contrast subjects, exactly the ones long exposure shooters care about, are where this hurts the most.
When the Built-In Trick Is Enough
To be fair to it: if you're at a waterfall on vacation and want one smooth-water shot for the family album, the Live Photo method is great. It costs nothing, requires nothing, and works on photos you already took. For casual, occasional use, start here.
When You Need a Dedicated App
You'll know you've outgrown the Live Photo trick when you keep bumping into the same three walls: not enough time, no control, no editing headroom. A dedicated long exposure app addresses all three. Using Lento as the example:
- Exposure time you choose. Anywhere from 1 second to unlimited, plus a Bulb mode for starting and stopping by hand. Five seconds for traffic, several minutes for clouds, as long as you want.
- Real-time preview. Lento stacks frames from a continuous 30fps capture using the GPU, and you watch the exposure build on screen while you shoot. No more converting and hoping.
- Blend modes for different subjects. Smooth (mean blending) for silky water and clouds, Light Trail (lighten blending) for headlights and light painting, and Ghost Remove (median blending) to erase moving people from a scene. The Live Photo effect gives you one fixed look.
- Manual control and RAW. ISO from 100 to 3200, manual focus, and 16-bit DNG export at 12MP with full EXIF, so your edits have real room to work.
One practical note: because each captured frame is exposed normally before stacking, handheld shooting is workable in Lento too. A tripod still wins for very long exposures, but you're not locked to one.

Frequently Asked Questions
Why don't I see the Long Exposure option on my photo?
The effect is only available on Live Photos. If the picture was taken with Live Photo turned off, or it was sent to you in a way that stripped the Live data, the option won't appear. Check that the Live badge shows on the photo, then look in the Live menu in the top-left corner.
Does converting to Long Exposure delete the original?
No. The conversion is reversible. Open the same Live menu and switch back to Live, Loop, or Bounce at any time, and the original frames are still there.
Can the Live Photo effect do a long exposure longer than 3 seconds?
No. The effect can only use the footage inside the Live Photo, which is about 3 seconds. For longer exposures you need a dedicated app like Lento, which has a free version (Smooth and Light Trail modes, exposures up to 5 seconds) and a Pro tier at $9.99 per year or $29.99 lifetime for unlimited duration and RAW. It requires an iPhone XR or newer on iOS 18.
