In most cases the dating of a Polaroid SX-70 photograph is accomplished by deciphering the manufacturing code found on the frame located on the reverse side of the photograph. However, instances arise where the numerals are either faded or obliterated to the extent that the reading and deciphering of such numbers are impossible. Research has determined the existence of chemical pod codes which can also be used to date Polaroid photographs.
