Remarks[edit]
- Most acetate-based films seem to be approx. 0.150mm thick, while the polyester-based films are usually thinner
- When a magnetic sound-stripe gets glued onto the film, then -in most cases- the film also becomes thicker.
- The scales on most film-reels are only applicable for unstriped acetate-based film-stocks. Hence, some film-reels have two or even three scales (the second for striped acetate-based films and the third for unstriped polyester-based films), e.g. the ones made by Posso.
- Some films have got an anti-halation-layer that gets removed during processing (see here). Hence, some of these films becomes thinner.
- In the 1960s/70s, some labs (e.g. the ones owned by Agfa and Kodak) used to apply a special scratch-protection coating to the processed super8-/16mm-films. In most cases, this was some kind of wax that increased the thickness. This is sometimes still done for 35mm prints.
- Some films are "stiffer" than other films. As a result, Super8-/Single8-cartridges might hold less film than theoretically possible.
