Photos blur effect background with camera phone

hello buddy steemians wherever you are

how to do lens blur by using a smartphone, but not with all types of smartphones can, yes at least a middle-class smartphone

I do it myself using my iphone 5 camera
his way when taking pictures on the screen smartphone just press the focal point on the object image when the background has started blurred direct check

***

but unfortunately the photo of the focal point of the lens blur with a smartphone camera can only be generated from a very close object distance, meaning a small object that fits in the camera screen that does not cover the background

maybe a photo with a high-end smartphone camera can take a human image with the focus blur background, meaning that the distance does not have to be close to the object image
