Hi! Thanks for reading. This post looks better in our award-winning app, Tips & Tricks for iPhone.
You can use the multiple frames of a Live Photo to replicate the effect of a long exposure shot on a conventional camera.
The feature is best used on images where only parts of it are moving, like a running stream. The result is that your device will essentially blur this part of the image, creating a unique look.
Find a Live Photo in the Photos app, swipe up from the bottom and then choose the option Long Exposure.
