When the pinhole is made larger, more light can enter through it, resulting in a brighter image. However, the increased size can also lead to a loss of sharpness and increased blur, as the light rays converge less precisely. Consequently, while the overall illumination improves, the image quality may deteriorate due to reduced depth of field and increased diffraction effects.

As the distance between an object and a pinhole decreases, the image formed on the other side of the pinhole becomes larger and more focused. This is because the light rays from different points on the object converge at different angles through the pinhole, creating a sharper image.
find it you self......
Make the hole smaller.
It would be upside down
The diameter d of the pinhole is the width of the hole.
Double image.

A pinhole microscope works by allowing light to pass through a small pinhole aperture, which then forms an inverted image of the object placed in front of the pinhole. This image is usually projected onto a screen or detector for observation. The pinhole limits the amount of light and enhances the depth of field, resulting in a sharper image.
Camera means "room" The first pinhole camera was made by someone who's name we do not know. Any room that has opaque walls and a relatively small opening on one side will exhibit the "pinhole camera" phenomenon. This was noticed in ancient times and commercialized in the renaissance.
a pinhole camera has a very small aperture for the light to pass through. Thus the sharp focus distance is very great too. You will get a bigger image if you move your paper or whatever the image lands on, further away from the pinhole.it may not be as bright, though
