Which of the above happens when the hole of a pinhole camera is diminished?
Answer Details
A pinhole camera is a simple camera device that uses a tiny hole to project an inverted image of the scene in front of it onto a surface at the back of the camera. When you diminish the hole of a pinhole camera, meaning you make the hole smaller, a few effects occur on the resulting image. Here’s what happens:
Firstly, when the pinhole is smaller, less light enters the camera. This results in the image becoming darker.
Additionally, with a smaller hole, the path of light rays becomes narrower which helps to reduce blurring and overlaps from being out of focus. Consequently, the image becomes sharper.
Therefore, reducing the size of the pinhole in a pinhole camera results in the image becoming both darker and sharper.
