Pinhole Cameras

History of pinhole camera: In the 5th century, the beginning of modern photography is ongoing. The first record of the pinhole experiment was recorded in the 10th century when Yu Chaolong used a model tower to record a pinhole image on the screen. In addition, Arab physicist and mathematician Alhazen (Ibn Al-Haitam) used a pinhole to observe the ecliptic. He arranged the three candles in a row, placed a small hole between the candle and the wall, noting that the image was formed only through a small hole and the right end candle left an image on the wall. And it guides the linearity of light.

The only difference between the camera's black box and the pinhole camera is that the camera's black box uses lenses, whereas the pinhole camera is a similar device but with an opening. This technology was developed when using these devices to draw project drawings that artists can trace in the 17th - 18th centuries. The only problem with this system is that there is no way to store images besides tracking. French inventors are widely accepted as creators of photography, as we know today. He used a self-made camera to make the first partially successful photo in 1816 with silver coated paper. This picture no longer exists, but Niépce's letter to the sisters proved to be a successful photograph. The first surviving photograph was taken by Niépce and is now a permanent exhibit at the University of Texas at Austin. It dates back to 1826 or 1827, his window in Burgundy.

The first 'camera' is the camera's black box or pinhole camera. This device in the history of photography is said to be able to go back to ancient Greeks and ancient Chinese. The device projects the image using pinhole, but the resulting projection is reversed. Alhazen or Ibn Al-Haytham is an authority in the field of optics and is said to be known in the history of photography as a person who later produced a pinhole camera in 1000 years later. In the early stages of photography, black boxes of photographs, particularly used in 1544 for the appreciation of food by the University of Leuven Reiners Gemma Frisius, suggested using this device as an aid to scientific painting in 1544 did. In 1685, Johann Zahn conceived the first small portable camera. This is close to a compact camera known today.

Let's consider a pinhole camera. It fly in the face of modern progress. However, it is still a tool with significant production value and critical lifetime. The pinhole camera or the camera's black box is actually a dark space. So you can create this dark area. A corrugated cardboard box having an opening on one side and directing the light flow to the opposite side wall on which photosensitive paper or film is attached. This will invert the image of the object. Photosensitive paper or film produces a negative image during processing. You can also change the SLR or DSLR camera to use as a pinhole camera
