Make your own Camera Obscura and welcome yourself to the upside down. Grab a Lens from Bonfoton some tinfoil and water to make your first tests, in 5 minutes you are in full inversion immersion. Check out peoples images of the Bonfoton lens in use. For a nice sharp Image it’s best to have a wall around 4 meters from the window, works well at different distances but the image isn’t as sharp.
