Hey mate!! This is AANCHAL PARMAR ANSWERING YOUR QUESTION.. Hope This Helps you
Edwin Land created first Polaroid Camera.
He had an idea of instant photography and asked Kodak company for funding. Kodak thought of it just as a toy to play with and laughed at him. So, Edwin Land went home and started working on side projects. He created Polaroid Lens and stuffs and collected money. Then he launched his first Polaroid Camera.
It became an instant hit. Kodak decided to steal the idea and made their own cameras. Edwin Land sued Kodak and earned a big fat money.
OR,
A Polaroid is a material which polarises light. The phenomenon of selective absorption is made use of in the construction of polariods. There are different types of polaroids.
A Polaroid consists of micro crystals of herapathite (an iodosulphate of quinine). Each crystal is a doubly refracting medium, which absorbs the ordinary ray and transmits only the extra ordinary ray. The modern polaroid consists of a large number of ultra microscopic crystals of herapathite embedded with their optic axes, parallel, in a matrix of nitro - cellulose.
Recently, new types of polariod are prepared in which thin film of polyvinyl alcohol is used. These are colourless crystals which transmit more light, and give better polarisation.
Uses of Polaroid
1. Polaroids are used in the laboratory to produce and analyse plane polarised light.
2. Polaroids are widely used as polarising sun glasses.
3. They are used to eliminate the head light glare in motor cars.
4. They are used to improve colour contrasts in old oil paintings.
5. Polaroid films are used to produce three - dimensional moving pictures.
6. They are used as glass windows in trains and aeroplanes to control the intensity of light. In aeroplane one polaroid is fixed outside the window while the other is fitted inside which can be rotated. The intensity of light can be adjusted by rotating the inner polaroid.
7. Aerial pictures may be taken from slightly different angles and when viewed through polaroids give a better perception of depth.
8. In calculators and watches, letters and numbers are formed by liquid crystal display (LCD) through polarisation of light.
9. Polarisation is also used to study size and shape of molecules.
Anyway, the film is made up of many layers. This film has to capture 3 basic colors: Red, Green and Blue. It absorbs these 3 colors separately on different layers as shown in the image below.
This film is then passed through a layer of chemical, which we use in the dark room. The advantage is this that, this was a moving dark room! Between a pair of rollers it can easily created a photo in 3 seconds!

sure
do the photos taken on a Polaroid fade or vanish after some time???
no....
ok
thank you again
polaroid pictures are archival
anytime

material in thin plastic sheets that produces a high degree of plane polarization in light passing through it.
The instant camera is a type of camera which uses self-developing film to create a chemically developed print shortly after taking the picture. Polaroid Corporation pioneered consumer friendly instant cameras and film, and were followed by various other manufacturers
The working of polaroid cameras[1] is very simple, it works as a model for our eyes. It uses a thin film which is made up of layers which can capture RGB colors. Then with the help of chemicals these captured colors can form an image.
