What is Camera Obscura?
Step inside a darkened room.
Let the sunlight in through a small hole and, an image will appear on the opposite wall. a Very dark and upside-down image.
Now, if you make the hole larger and put a LENS over the hole. The image will be much brighter and sharper. Yet, it remains upside-down.
If you use a LENS + PRISM combination (=BonfotonUP), the bright and sharp image will be seen right-side-UP!

"I'd say the BonfotonUP device would be an excellent tool for a physics class in high school with the possibility to visualize the theory behind the phenomenon."
"Making pinholes is necessary for learning about photographic principles, but the Bonfoton devices are a better way of sharing that experience and living it.
I really think every school should have one."

"I really enjoyed getting creative with the Bonfoton lens. We set it up in a rural location and projected the drama of the outside world on the sheltered, warm inside of the shack we were in. We could have watched the scene for hours it was so dreamy! Thanks to Bonfoton for creating this dream maker!"
