Instant photos are photo papers exclusively for instant photos, and film is the direct light-sensitive material in ordinary cameras

It is roughly divided into negative film and reversal film (black and white

or

Color) people commonly use negative film. The image reflected on color negative film is the complementary color of the real image color

That is, the opposite color. The same goes for black and white negative films

Black things are reflected transparently on the film.

Take the film to a photo lab for development, and then project and enlarge it onto photo paper (the principle of photo paper is similar to that of film) and the resulting photo will be restored to its true color. Instant cameras do not use film

There is no film either

Only photo paper

But the photo paper is different from ordinary photo paper

p>

The Polaroid photo paper is made of two layers

There is a pack of potion at one end of the photo paper

When the photo is finished

Take out the photo When

being squeezed by the camera roller

walking between two layers of photo paper

chemically reacting with the photo paper that has been exposed to light

Reveal the image

The potion will not be squeezed out

Because there is a strip of medicine bag at the other end of the photo paper to store the used medicine. The liquid in the Polaroid photo paper is very toxic

So try not to play with it.
