TidBITS:

I pulled my iPhone 8 Plus out of my pocket and took one exposure, handheld, with the Live Photos feature turned on. And then I applied Apple’s new Long Exposure effect in the Photos app. That’s it. The Long Exposure effect is dirt-simple to use.

Anyone who has used a DSLR to take long exposure shots will look at this technique with a little bit of envy. The iPhone shots aren’t perfect but they are damn good all things considered.
