You can get a really cool effect by aiming the camera at a window and taking a picture of the reflection

I was in the 30th floor of a hotel in a big city.My father was sitting on a chair near the window. On an impulse I took a photo of him but accidentally took a photo of the window.He was still in frame but the silhouette of the skyscrapers outside the building were reflected in the photo as well.It looks Photoshopped but I didn't even do anything,it was all just using the window and my phone camera.I think this only works at night and in a big city and you are staying in a high rise. via /r/photography https://ift.tt/2IFpFOS
