The Camera Obscura - AstroMedia
Pre-cut cardboard kit for the mother of all cameras with reflex optics for image uprighting and perspective-correct drawing of motifs
The first camera
Our photo, film and video cameras all have a common ancestor: the camera obscura. Aristotle (384-332 BC) was the first to study it scientifically, and Leonardo da Vinci discovered that it is reflected as an optical principle in our eyes. In 1686, Johann Zahn constructed the first camera obscura, which allowed subjects to be easily traced with the aid of a mirror. Around 1750, painters such as the Venetian Canaletto used the camera obscura to sketch the perspectives for his famous cityscapes. When the Frenchman Nicéphore Nièpce directed the image onto a light-sensitive plate for the first time in 1836, the camera was invented.How it works
Light from the outside world falls through a small hole onto the opposite wall of a room, creating an upside-down image. In this design, the image is projected onto a ground glass screen using a mirror, where it can be viewed and traced. The included lens makes the image particularly bright and sharp. For an optimised and interference-free view, we also recommend our night-black velour paper.You can find a detailed illustrated construction report here.
