You can figure out why an image in a pinhole camera is upside down if you think about how the light travels to get to the image.
Light from an object higher (or the top of the object) than the camera travels in a straight line down to the camera. It goes through the pinhole and continues heading down until it hits the back of the camera. This means that the image of something higher than the camera is now low in the image. The opposite is true for light from an object lower than the camera (or the bottom of the object): it travels to a point higher in the image.
Still does answer my question, how did the image get upside down? answer was no concusive.

I think a pinhole camera is similar to the human eye because like the pinhole camera when it sees something it reflects the image but it is an inverted image. With the human eye the brain corrects it and turns it the right way up. The pinhole cameras image is not corrected because it does not have a lens.
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
Yeah, easiest is to build a pinhole camera. http://www.pinhole.com/ Or read: "Pinhole Photography" by Eric Renner
A focusing screen in a pinhole camera? Uhh...no. A pinhole camera is a box with a very small hole in one end of it and a piece of film in the other end. The screens in reflex cameras and in view cameras are translucent to give the image something to form on. The light will pass through a transparent screen without forming an image, and it won't go through an opaque screen at all.
The image will be formed upside-down and reversed horizontally on the back of the inside of the camera.
A polaroid pinhole camera is unique because it uses a pinhole instead of a lens to create images. This creates a soft, dreamy effect in photos. The benefits include a vintage look, simplicity in design, and the ability to create artistic and experimental images.
The optimal size for a pinhole in a pinhole camera is typically around 0.5mm to 0.3mm in diameter. This size allows for sharper images and better light exposure without causing excessive blurring.
A pinhole camera works by allowing light to pass through a small hole (the pinhole) and project an inverted image onto a surface inside the camera. The image is then captured by the surface, such as film or a digital sensor, creating a photograph.
The pictures that are seen in the pinhole camera usually show the colors of the objects in front of the camera. The images usually look slightly blurry compared to the real colors.
A pinhole camera works by allowing light to pass through a small hole (the pinhole) and onto a light-sensitive surface inside the camera. The pinhole acts like a lens, focusing the light to create an image. The image is then captured on the surface, such as film or a digital sensor, without the need for a traditional lens.

The instax pinhole camera offers a unique way to capture photos with a vintage aesthetic. Its pinhole lens creates dreamy, soft-focus images with a nostalgic feel. The camera is compact and easy to use, making it great for creative photography projects. Additionally, the instant film allows you to see your photos develop right before your eyes, adding a sense of excitement and immediacy to the process.
A Pinhole camera.
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.
