Hey,
I made this gif whit my iPhone SE. By photographing whit the live function you get also a row of images in whits you can pick the best one for the picture. I mostly use this function for my children, its more a movie function then.
When you look at the picture in the foto's app you can swipe up on the image. Here you can make different functions with these live foto's. Here I used the loop function, which make's a interesting result if you asked my.
