Camera obscura consists of a wooden square box with a brass tube lens mounted in the center of one side. Images that enter the brass tube are projected through the spherical glass lens onto a first-surface internal mirror. The image is then reflected onto a screen of ground glass where the observer can interpret and capture the perspective, composition, and much more.
The camera obscura was also the great-grandfather of modern cameras. And with this project, we're creating a way to capture the camera obscura's magical image with a push of a button. And the result is truly breathtaking!
