The story starts 15 years ago with a photo from my window. I kept this technique and photos away from public as I wanted to show it to the World first. And what a better way to do it with the greatest city in the World, New York!Some of the photos are on film, but most of them are digital, but it is a macro photography technique, not a Photoshop, that is why it has flaws in sharpness and a lot of blurs.
