How was the image produced in a pinhole?

Since a pinhole  camera is a simple camera without a lens but with a tiny aperture, a pinhole is effectively light proof box with a small hole in one side.Light from a scene passes through the aperture and project an inverted image on the opposite side of the box which is known as camera Obscura. The produced images have some characteristics,this include,they produce   inverted images, this is because light travels through air in a nearly perfectly  straight line,the light  that travel from the top of the tree ,straight to the top of the image and also the image is upside down and back to front in all camera.

Cool research, it is super interesting how a type of paper exposed to light and then developed with chemicals can show the image of the light it was exposed to. I like how you explained how a pinhole camera works, it is concise and easy to understand. I remember when I first learned how to use a pinhole camera in the form of a cardboard box with a hole. My first picture was grossly overexposed but, after a couple of attempts, I found the right time to expose it to light. It is also interesting that, depending on the size of the box, the duration of exposure varies. I find it interesting also that they are so easy to make. Here is a link to a video that shows how to make a pinhole camera. As you are studying this you may find it interesting.

I hope this helps to inform your research!

I remember making one of these! Something that I didn't think about was how still the camera has to be to get a clear picture. When I took my first picture, I held the pinhole camera rather than placing it on the ground. This resulted in a blurry picture. I recommend finding a steady place to put your camera when taking photos. Just something to think about.
