Microsoft's Office Lens is an app that was designed as a scanner: you would use it to take pictures of documents, business cards and presentations cast onto a screen. The app detects the edges of the slide/document/card, analyses the tonality of the image and then trims and enhances it, producing a neat, squared image. It's very good at that.
I decided to shoot Berlin with Office Lens - let it do its thing, and see what happens. I really like what it does with buildings shot from street level.
I shoot for fun, with a Sony A7II, a Mavic Pro and my trusty iPhone 6s.
