The new Live Focus allows users to set and adjust the
intensity of background blur of captured images, both before and after the photo is taken.
Inside the camera app you'll find a slider that lets you adjust the
amount of background blur in your shot, both before and after you snap it.
The camera app has a portrait mode that adds a depth effect and
lots of background blur while keeping the subject in focus.
The Note 8 has the ability to adjust the intensity
of the background blur before and after the shot, and Apple has added studio lighting effects to iPhone X.
It is worth pointing out that «standard» iPhone pictures have a nice level
of background blur automatically, with the focal length automatically finding a nice depth of field for whatever you're trying to snap.
This means keeping the subject in the foreground in focus, but adding lots
of background blur via software, as applied from a depth map created by offsetting the data of both cameras.
That telephoto lens allows you to have plenty of control of Bokeh blur, with a Live Bokeh mode allowing you to tune the level
of background blur in your shots.
It actually features a Live Bokeh mode, which allows you to fine tune the level
of background blur with instant visual results on screen, allowing you to set up your picture before hitting the shutter key.
For example, you can add DSLR - like bokeh effects to your photos through Samsung's Live Focus feature, and change the amount
of background blur even after taking a picture.
There's a portrait mode in the form of live bokeh, again using the two lenses to give you a depth map and choose how
much of that background blur you want.
Similar to the Live Focus feature on the Samsung Galaxy S9, the Nuu G3 allows you to adjust the
degree of background blur and see the results instantly in the viewfinder.
The S9 + also adds a secondary telephoto lens on the back, which allows you to really focus in on the subject of a portrait while adjusting the strength
of the background blur before or after taking the shot.
The
level of background blur is on par with more recent devices such as the Google Pixel, but isn't as pronounced as the bokeh we see with smartphones offering a software enhancement.
