A polaroid camera is a type of camera with self-developing film. The most famous are those made by the Polaroid Corporation. The invention of modern instant cameras is generally credited to American scientist Edwin Land, who unveiled the first commercial instant camera, the Land Camera, in 1947, 10 years after founding the Polaroid Corporation.
Taking an instant photograph
Edwin Land's original idea behind instant photography was to create a photographic system that was seamless and easy for anyone to use. The first Roll film cameras required the photographer to use a light meter to take a reading of the light level, then to set the exposure setting on the lens. Then the lens was focused and the subject framed in the popular medium format. After the picture was taken, the photographer flipped a switch and pulled the large tab in the back of the camera to pull the negative over the positive, through some rollers to spread the developing agent. After the picture developed inside the camera for the required time, the photographer opened the small door in the camera back and peeled the positive from the negative.
Pack film cameras operated in a similar manner except for the fact that most of these cameras had automatic exposure. The development of the film required the photographer pull two tabs, the second tab which pulled the positive/negative "sandwich" from the camera, where it developed outside the camera. If the temperature was below 60°F, the positive/negative "sandwich" was placed between two aluminum plates and placed either in your pocket or under your arm to keep it warm while developing. After the required development time (15 seconds - 2 minutes), the positive was peeled apart from the negative.
Integral film cameras, such as the SX-70, 600 series, Spectra, and Captiva cameras went a long way in accomplishing Edwin Land's goal of creating a seamless process in producing photos. The photographer simply pointed the camera at the subject, framed it, and took the photo. The camera did the rest, including adjusting the exposure settings, taking care of focusing, utilizing a flash if necessary, and ejecting the film, which developed without intervention from the photographer.
Regular pictures are taken on 35mm film negatives and must be sent to a film processing place for development and printing.

The difference between a regular film photograph and a Polaroid photograph is in how the exposed film is developed. There is a process using chemicals to turn the exposed film into a picture. Ordinarily, you shoot a roll of pictures and take that film someplace to be developed in an hour or a couple days, depending on where you go. Those places take your film and create the photos.
A Polaroid camera uses film encased in special sheets. There is a small pocket of chemicals at the bottom of the sheet, contained in the wide area off the picture along the bottom. Once the camera exposes the film to light, when the photo is ejected from the camera, the chemicals are pushed from the pocket to cover the film. After a few minutes, those chemicals process the film and create an image.
Because Polaroid pictures keep the empty pocket that originally held the chemicals to make the picture, that pocket can be used to hold other things. It is simple to create a small hole, insert drugs into that pocket, and close the hole without leaving much trace. That is why they are not allowed in prisons.

The difference between a regular photo and a polaroid photo is that a polaroid photo is instant. When you click the button on the camera a few seconds later the actual photo will come out. The reason for their ban in jails is because at the bottom of the polaroid photo is a little pocket used to house the development chemicals. People trying to smuggle drugs or other items into jails simply cut into this pocket and place the items in there and seal it up again. Below is a link to what a polaroid camera looks like.

A Polaroid picture is one that you take and it instantly developes in front of your eyes as you watch. A regular picture is one that requires a film such as a 35mm, 110, etc. and you have to take them in to the store and have them developed. A Polaroid picture usually does not last as long as a regular picture, they are more apt to crack and loose color. My guess for the reason as to why they do not allow Polaroid pictures is the fact that the pictures themselves have a layer between the picture and the back and a person could put things such as drugs , razorblades, etc. in between the papers.

a regular picture is one that would have to be developed. a polaroid is one that comes out of the camera right away. my brother is in jail and the reason for that is...a polaroid can be peeled apart in half. there are times where someone tried to send some kind of drug in between the layers of the picture so the inmate can still use drugs.

A picture is like the ones that you get developed at pharmacies and are usually 4x6 and polaroids are pictures from polaroid cameras that pop out right after you take a picture. They self develop instantly. Are 4x4-ish with a white bottom part. Hope that helped!

Polaroid pictures are developed inside the camera with a chemical solution. dont know maybe they've found some weird use for the chemicals.
