Why is the pinhole camera black?
You should notice that the inside of the pinhole camera is painted black to stop unwanted reflections inside. It is also helpful to have a light shield over the back to shade the screen. The fact that the pinhole camera gives a clear image is very good evidence for the fact that light travels in straight lines.
How is pinhole camera different from real camera?
A conventional camera uses a glass lens with or without a shutter that directs the light to the recording surface. The main difference is that a pin hole camera has no lens and therefor no adjustable aperture to that of an conventional one.
How was the pinhole camera discovered?

Does a pinhole camera produce shadows?
The image formed by a pinhole camera is inverted compared to the object, but it has the same colour as the object. In addition, the image has all the details of the object. Hence, we can confirm that a pinhole camera forms an image, not a shadow.
Why do we see inverted image in a pinhole camera?
An inverted image is formed in a pinhole camera because the light rays coming from the top and bottom of the object intersect at the pinhole. Thus, we get an upside down image in a pinhole camera due to linear propagation of light through the hole of the pinhole camera.
