When the hole is enlarged, the picture changes, and the change increases with the added width.
Life before cameras
In any case, even in the best of cases, the camera's image is rather dim and if not duly shielded from the incoming light. Light entering the camera obscura through the hole projects onto the screen wall, and following the laws of optics produces and upside-down and reversed image. You will catch these pictures on a piece of white paper, which placed vertically in the room not far from that opening, and you will see all the above-mentioned objects on this paper in their natural shapes or colors, but they will appear smaller and upside down, on account of crossing of the rays at that aperture. If these pictures originate from a place which is illuminated by the sun, they will appear colored on the paper exactly as they are. Euclid is sometimes reported to have mentioned the camera obscura phenomenon as a demonstration that light travels in straight lines in his very influential Optics circa BC. Here the shape of the head is conceived in broad areas of light and dark, separated by softly rounded edges. When a foot soldier would stand in front of the camera, a twelve-person army of soldiers making the same movements would be projected. Other characteristics of paintings done by artists using a camera obscura include oddly large or small hands, the edges of buildings shrink towards a vanishing point, or a ring of yellow light in the middle of the image.

He compared the working of the eye to that of the camera obscura and seemed especially interested in its capability of demonstrating basic principles of optics: the inversion of images through the pinhole or pupil, the non-interference of images and the fact that images are "all in all and all in every part". Della Porta compared the human eye to the camera obscura: "For the image is let into the eye through the eyeball just as here through the window". The camera obscura is a device that projects an image of its surroundings on a screen. This device was attached to a wall of the camera obscura EF. I, Libri IV.
