Pinholekamerassa
Pinholekamerassa is a Swedish word that translates to "pinhole camera" in English. A pinhole camera is a simple camera that does not have a lens. Instead, it uses a small hole, typically called a pinhole, to project an inverted image onto a light-sensitive surface inside a light-tight box. The size and quality of the pinhole are crucial for image formation. A smaller pinhole generally results in a sharper image but requires a longer exposure time due to less light entering the camera. Conversely, a larger pinhole allows for shorter exposures but produces a softer, less detailed image.
The principle behind the pinhole camera is the rectilinear propagation of light. Light rays travel in straight
