4AM is a collaborative picture book by Anthony Geernaert and Chris Rubino documenting 15 years of late night urban exploration and image-making.

The images in this book, at the moment of their making, are invisible to the naked eye, ephemeral sketches that only come to life through the photograph.

Spanning many years and many places when put together they tell a story of time, place, and momentary release.

As a full collection, the images are a celebration of the unexplored world and its many hidden quiet corners.
