Long exposure of photography first, what is it?
Well, any camera, whether it's the one on your phone or any other digital or film camera, has what's
called a shutter inside it.
And when you take a photo, the shutter opens for a split second and then closes.
And this allows light to pass through the lens and expose your image.
So long exposure.
Photography is when the shutter stays open for a longer period of time.
Why is this useful?
Well, it allows you to take images like this where moving objects in the scene draw lines across the
image or like this where running water appears to flow like silk.
This is because the water is moving while the shutter stays open and it blurs across the image before
the shutter closes.
But anything that's not moving will stay perfectly in focus.
And believe it or not, this can be done on an iPhone.
So let me show you how.
So first, just click on the camera app.
And then just turn on live photo op at the top, right, and then just take a shot and then view that
shot.
And then just swipe up, and if you scroll through this little effect's list here, you're going to
see long exposure over here all the way to the right.
Just click on that and then it's going to instantly blur all of that moving water and give you a beautiful
shot.
And the reason it does this is because live photo takes multiple pictures and then combines them all
into one photo.
And anything that's moving is going to be blurred.
And then anything that's sitting still is going to stay perfectly in focus.
