The LG V40 ThinQ portrait mode is available on both front and rear camera. I am showing you the rear camera operation; the front operation is the same.
Open the camera app and tap the “Portrait” sign on the screen:
Tap the headshot icon to select different background option:
You can select the background color;
You need to move the camera towards or away from the person until the camera says portrait mode is available. Take the photo.
Here is a sample photo of me and my nephew’s dog.
I like the pleasing effect of the bckground. In this photo the camera mistakenly replaces the bottom right of my body with the background. I can probably photoshop something there. Other photos I have do not have this fault but have photos of others which I cannot share it here.
However, this may be enough for you to try it out and hope you will have lots of fun.
Enjoy & Bye for now.
