Thus, the company published its Background defocus app in the ay store. The app lets you select the object that remains in focus while the background gets blurred out. After you snap the photo, you can then adjust the blur level blur effect. For best results, Sony says to shoot the object from 0.5- to 1.5-feet away. The app only works with Sony’s Xperia devices, so if you were looking to download it for your other-br phone, you’re out of luck. Sony’s really angling to get consumers to notice its Android devices for their camera abilities, so this is the best way to remind everyone that its phones are just as capable as the others out there.
