In a camera, the light from the subject is refracted by the camera lens, and focused on the film or digital receptor inside the camera. The lens is taking the "large image" and shrinking it to a smaller size, and this small image becomes the digital image (or the negative image on film).

How a Camera Works

A camera is any sort of light tight chamber (the word camera means "chamber" in Latin) with a pinhole or convex lens in one side. The lens is what "forms" the image on the opposite side of the camera. Your eyes are cameras! They are light-tight chambers with convex lenses which form continuous images on the retinas (light sensitive surfaces) at the backs of your eyeballs. Because of the way light passes through a pinhole or lens, the image is projected to the back of any camera upside down. This is just as true in your eye as it is in your camera! But, you protest, I don't see upside down! No, you don't, because your brain "flips" the image right side up as it comes from your optic nerve. Your digital camera does the same thing electronically before it delivers the image to your viewscreen.

Sight, and your camera, works because objects reflect light. Even black objects reflect some light. Lighter colors reflect more. The pinhole or lens in any camera is gathering light as it comes reflected from a scene. The light reflected from the scene is scattering in all directions, but as light from what you see reaches the pinhole or convex lens in your camera or eye, you can try imagining that the light rays from the scene must bendand squash down (we say converge) in order to pass through the pinhole or lens. Inside, the light rays must cross, which is why the image projected to the back is upside down. If the lens is the correct distance (focused) from the back of the camera, the lens will form a sharp image on the side opposite the lens, which can be your retina, film in a film camera, or the sensor in a digital camera.

There's lots more to know. See the Related Question, and be sure to check out the Related Link below. It has a fun, easy project for any age for making a pinhole camera that you can look inside and actually see the upside down image projected onto a translucent screen made of waxed paper.

Depends on the film ...

but in general light precipitates silver atoms out of the solution that coats the film during exposure.

Developing the film consists of washing every else off.

They type of image formed in a camera is actually upside down. When we see it is transversed to be the right away. It has to be transversed to because of the light that takes the picture.

Why the image formed on the screen of the pinhole camera is inverted?

The image formed on the screen of the pinhole camera is inverted because the aperture, which is a small hole, bends the light that enters the camera. This basically shows that light travels in straight line.
