The origins of the camera obscura in China – Study how and why
Product Details: The camera obscura is a device consisting of a closed box with a pinhole, capable of projecting light and creating an inverted image on a projection plane. The concept was first described in ancient Chinese writings, notably in the ‘Mozi’ attributed to Mozi around 476 BC – 221 BC. It explains how the inversion of the image works through the projection and collection by means of a pinhole camera. The device was later described by Aristotle in the 4th century BC and further developed by scholars such as Alhazen, Shen Kuo, and Leonardo da Vinci. The camera obscura evolved from
large rooms and tents to portable box forms, using lenses and mirrors to improve image quality and projection[2].

HISTORY OF THE PINHOLE CAMERA
Product Details: A pinhole camera is a simple optical imaging device in the shape of a closed box or chamber with a small hole on one side. This hole, via the rectilinear propagation of light, creates an inverted image of the outside space on the opposite side of the box. The technique is based on the principle of the camera obscura, which has been known since ancient times. The first commercial pinhole cameras were designed in the late 19th century, with notable examples including the ‘Photomnibuses’ and the ‘Glen Pinhole Camera’. Pinhole cameras can be used for various purposes, including artistic photography,
educational tools, and even scientific applications such as capturing high-energy X-rays and gamma rays.
Pros:
– Allows for unique and artistic photographic results due to the distinctive chara…
