Samsung's Galaxy 8 Dual Cameras are a Shot Across the Bow of the iPhone 7.

You can't make a successful smartphone today without having a game changing camera, and I mean game changing. In the world of Instagram and Snapchat, people use the cameras on their phones every day. Literally EVERY day. Can you imagine going back in time, even thirty years ago, and telling someone that in 2017 they're going to take multiple, possibly dozens of photos every day in the future? Their first reaction would a confused "of what?" and their second reaction would probably be to laugh when you said, "yourself and food." 

Samsung doesn't live in the past anymore and knows that if you really want to take great pictures of yourself and food every day, you need two cameras and the Galaxy Note 8 looks to finally deliver all the high ISO, fast shutter and shallow depth of field pictures that you need.

Ok, technically, that's a beverage, but it still looks pretty great. 

The iPhone 7 Plus has been able to take blurred background shots now or "portrait" images since its introduction almost a year ago, and Samsung is doing one better. With its 'Live Focus' mode, you'll be able to control the dual 12-megapixel cameras with a slider opening up the aperture all the way down to f1.7 to create maximum blur... even after the picture is taken!

This is possible with a feature called Dual Capture, where the camera is actually taking two images, one with each lens. Now the reason for two lenses is that one of the lenses is a wide angle and the other is a telephoto. Because of size limitations of the lenses and the space in the camera you need two lenses to achieve the same look you'd get from a medium lens on a DSLR and this is what they look like. 

With screen specs sporting a 6.3" Quad HD+ Super AMOLED (2960 x 1440) 521 ppi
on a near bezel-less, full-frontal glass, edge-to-edge screen. Samsung might be taking the lead in what you see is what you get smart phone images. Look at this gallery taken by Samsung, with the Galaxy Note 8.
