 Around 1960, the very first screen shots were taken using interactive computers. Computer operating systems didn't always have the capability of capturing images prior to the 1980s. Sometimes , screens that only contained text could be dumped to a text file, however, the result would record the contents of the screen, not its appearance. Neither could graphics screens be saved by this method. Certain systems included the BSAVE command that could be utilized to take the memory area where screen data was stored however this required access to the BASIC prompt. Systems that had composite video output could be linked to a VCR and the entire screencast could be preserved using this way.Screenshot kits were made available for regular (film) cameras that included the long hood with anti-reflective that could connect between the screen and camera lens, and lenses for close-ups for the camera. Because of its speedy results and ability to focus closer, Polaroid film was a popular choice for capturing screen shots. In 1988, Polaroid introduced Spectra film featuring a 9.2 x 7.3 image size more suited to the 4:3 aspect ratio of CRT screens
