Pinhole
Pinhole, also known as Camera Obscura, is the technique that allows light to penetrate through a small hole and project an upside-down image on a wall of a completely dark room. That’s how this technique of photography was invented. At present times Pinhole technique is used by photographers not only out of curiosity but also for taking especially artistic pictures. The cameras are being produced from various kinds of objects – boxes from coffee, tea, tobacco, or any other suitable package. A hole is drilled in a box and light-sensitive material is placed inside the object. While taking pictures using this way the image can be captured (exposed) for a very long time: for a minute, an hour, or even a day.
