WebOct 5, 2024 · To generate clear and sharp images the diameter of the aperture (hole) of a pinhole camera should be as small as possible. If we increase the size of the aperture, we know that rays from multiple points of the object would be incident on the same part of the screen creating a blurred image. Understanding how is aperture measured can be confusing at first. This is because aperture is measured in what is known as f-numbers or f-stops, which is the ratio of the lens’ focal length divided by the effective aperture diameter.
