All documents up to A3 size are microfilmed on high-resolution planetary cameras, with a 16mm roll of microfilm containing up to 3000 frames.

Engineering drawings, maps and architectural plans up to A0 size are microfilmed onto to 35mm roll film. With plans and drawings the 35mm roll film can then be either inserted into microfilm jackets or mounted onto microfilm aperture cards where, each drawing can be individually indexed. The microfilm jackets (originals) can be duplicated onto diazo microfiche for every day use and distribution to other offices.

Normal usage for 105mm film is for technical manuals, operation handbooks, troubleshooting flow diagrams, etc. The images are arranged permanently in a grid pattern. The 105mm film usually has a coloured header that contains identification information (title). Step and Repeat microfiche can hold up to 300 frames.

An aperture card is like on old punched card but with a 2"x2" piece of 35mm film set on one side. The aperture cards are generally used for the storage of large format documents.
