Looking back at Apple events from the past couple of years, it is evident how the company's focus on the smartphone camera has grown exponentially. Apple yesterday unveiled three new iPhone models – the premium iPhone Xs and Xs Max and the more affordable iPhone Xr. But since the Xr has a single camera on its back, and is not meant to be on the bleeding edge of technology in this regard, we are going to be focusing on the iPhone Xs and Xs Max instead. Just like Apple did in the keynote.
