A pinhole and a camera both determine how much light comes through to make a picture, if there isn't enough light in you photo . The photo wont show.
To create a pinhole camera film, you will need a light-tight container, a piece of photographic film or light-sensitive paper, and a small pinhole to let light in. The container should be able to hold the film securely and prevent light from entering except through the pinhole.
The Pinhole Camera - 2008 was released on: USA: 17 November 2008 (Santa Fe Film Festival)
The first cameras were pinhole cameras. They worked by the light from the image on the outside enters through the pinhole and flips it on to the film on the inside and the film captures it.
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.
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.
Yes, the image on the screen of a pinhole camera is upside down because of the way light passes through the small aperture and projects onto the film or sensor inside the camera. It is a characteristic of pinhole cameras due to the nature of how light travels through a small hole.
The daguerreotype.
In a pinhole camera, the size of the hole has the same effect as the aperture setting on a more traditional camera. The size of the hole, combined with its distance from the film or sensor, controls the depth of field of the image and the length of exposure needed. Smaller holes will result in greater depth of field (to a point) and longer exposure. To compare a pinhole camera to a traditional camera, the distance from the film to the pinhole gives you the focal length, the size of the pinhole divided by the distance to the film gives you the effective aperture which can be used to determine the exposure needed. The reason that I included the "to a point" when discussing depth of field is that the pinhole must be in a very thin material and should be blackened in order to limit loss of sharpness due to diffraction. Diffraction also contributors to a loss of sharpness in traditional lenses when stopped down past f16 or so.

Think in terms of ray tracing. Light travels in a straight line in a pinhole camerabecause there is no refracting or reflecting optical element to change the path of the rays of light. The bottom of the film is on the line passing through the pinhole and top of the object. Since all light must pass through the pinhole, that means the top of the object exposes the bottom of the film.
