why cannot a pin hole camera take picture in the dark?how can we obtain an erect image in a pinhole camera?
Pinhole camera uses the principle of rectilinear propagation of light . A pinhole camera consist of a small hole through which the light passes and fall on a piece of film in side the camera . When an object is placed in front of pinhole camera , from each point of the object , ray of light pass through and fall on the film of the pinhole camera . When there is dark no light will pass through the hole and hence no light will fall on the film of the pinhole camera. Therefore no image is formed .
A pinhole camera always form a inverted image it does not form erect image .
