At the rate at which mobile phones are been upgraded and improved, it is only normal for users to expect more. Aside the battery life, users put into considerations the camera quality of a device before purchasing it.
It is not a mystery that many brands have incorporated different features and upgrades on their various devices.
The brokeh effect is one effect that was hyped by smartphone brands like Apple even though theirs was not really the real thing.
Interestingly, the brokeh is able to capture and focus on a subject while blurring the background.
Before now only DSLR camera could take portrait shot, but with the aid of dual camera smartphones can now carry out this task.
There are some thrilling effects that come with some smartphones; phones having these effects are usually high cost phones due to production cost.
It is not to say that low budget device cannot have this effect, but the truth is that most low cost phones comes with inferior cameras which would not compliment the brokeh effect. Another reason is that the brokeh effect is usually supported by a dual lens which most low cost device do not come with.
The live focus mode is made for a perfect brokeh, what this simply means is that the live focus is a feature of the brokeh effect. The live focus mode is mostly featured in flagship smartphones like Samsung and iPhone.
One Samsung device with an exceptional live focus is the galaxy note 8, the live focus allows users apply and adjust a shallow mode depth of field effect before and after snapping a photo.
Furthermore, the note 8 alerts you when the condition is appropriate for brokeh by sending a message above the blur slider. In fact, the brokeh effect uses artificial intelligence and works when there is sufficient light in the background, that way the live focus mode can function properly.
The recent galaxy S9+ also comes with the live focus mode making the brokeh better and giving you the power to control the background blur by either adjusting or readjusting the background blur to a level you want it to be.
Samsung Galaxy S9+ also comes with a feature that allows you choose from a range of background blur and shape that adds more beauty and defines your photo.
When the brokeh effect was introduces initially, it only allowed users to take out- focus image, these photos will remain with a blur background. The live mode now makes it possible for users to add brokeh effect during or after taking a photo.
Live focus performance on some smartphones
I mentioned earlier that the brokeh mode is usually supported by a dual camera, but it is no news that some brands like Apple, Huawei and Google have been able to achieve the brokeh in single lens phones.
That’s not all! These brands have also made it possible for front cameras and lenses to add brokeh to selfies. The optics and software algorithm of a smartphone contributes to a brokeh and portrait effect, the optics put into consideration size, space and lens of the phone.
Due to miscalculation of this optics, portrait mode on some low budget phones like
These phones have one of the worst live focus as they failed to out-focus the whole background and also leaving some background details out.
Top scorers of the brokeh or portrait effects are high cost device like iPhone X, Google pixel 2XL and huawei mate 10 pro.
The Samsung galaxy note gave a quite impressive brokeh which was not much of a problem with its high- end dual rear lens. This dual lens could even capture photo with brokeh effect without the aid of the live focus.
How to use the live focus on Samsung device
Open camera app
The first thing to note before initiating the brokeh on Samsung device like note 8 and S9+ is that the brokeh effect only works with the rear camera.
You can open the camera icon by either tapping the camera shortcut on the app drawer or launching the app by tapping on the camera icon on the home screen.
Live focus option
Once you have successfully opened the camera, tap the live focus button above the shutter, you will receive a prompt from the camera app telling you to stand at least four feet away from your subject.
Then switch mode will utilize the 2x optical zoom capability to get ready for Shot or you will see a live focus ready indicator to focus subject.
Control background blur
After the above step, use the slider above the shutter to control the background blurs, you can also adjust the background blur of the photo after you have captured it. You can do this by tapping the Adjust background blur option.
Factors that affects the use of live focus
There are some factors that should be considered before using the brokeh effect, depending on the smartphones. Users should note that all smartphones cannot perform brokeh one the rear and front cameras.
Camera that can carry out the brokeh both at the rear and front lens are iPhone x and Google Pixel 2XL, Samsung phones
When using live focus ensure that the subject is about 4 feet away from the phone, If this is not done the live focus will not function.
Another factor that affects live focus is lightening; live focus will not function in a poor light background or low light condition.
Users should also note that the camera zoom is fixed in the live focus and cannot be adjusted. For Samsung S9+ and note 8 users, you can also use the dual capture. The dual capture is able to both live focus image and wide angle image simultaneously.
