Black and White Photography with Lumia 1020

With all this hype about the new iPhone 6 and how its camera is the best ever yet, I can't imagine my life without my Lumia 1020. In fact everytime I post something on Instagram, people often ask me for the type of camera used to take the photo.
So recently I purchased an App called ProShot and it is simply amazing. Take a look at the black and white photo below and tell me how a $200 phone camera can do this:

One drawback is that you can't assign ProShot app to launch when the camera button is pressed. But I am sure the development team will figure this out soon.
