*Why to Blur Background?
Photos with soft, blurry backgrounds are perfect for making the subject stand out. A blurred background does not compete for the viewer's attention and can make photos appear more professional. Portrait photos, macro photos (flowers, insects, and food), low-light photos, and photos where you want to focus on only one detail all benefit from having a blurred background.
*Why do photographers blur the background?
When it comes to background blur the focal length of the lens plays a huge role. It plays as much of a role as the f/stop (aperture). The wider the angle of view, the sharper the background will appear at a given f/stop. The narrower the angle of view, the blurrier the background will become at a given f/stop.
*What is Blur Background?
There is a widget to take photo, AUTO segment foreground person(s) and apply blur background effect.
