What is a Camera Obscura and How Does it Work?
A camera obscura is an optical device that projects an inverted image of the outside world onto a surface inside, using a small hole or lens. This device works by allowing light to pass through the small hole or lens, creating an inverted image of the outside world on a surface opposite the hole. The image is inverted because light travels in a straight line, and the small hole or lens acts as a pinhole, allowing the light to pass through and create an inverted image.
The camera obscura has been used for centuries as a tool for artists, scientists, and architects to study the properties of light and shadow. It is also used as a teaching tool to demonstrate the principles of optics and the behavior of light. In recent years, the camera obscura has gained popularity as a unique and fascinating feature to add to homes, providing a unique perspective on the outside world.
