Making heads or tails of film orientation can be a topsy-turvy endeavor, but is crucial to ensuring proper winds, investigation of newly incurred damages, and accurately citing locations throughout a fil...")

- 19:18, 15 October 2025 Rfhall talk contribs created page 16mm aspect ratios (Created page with "The 16mm frame has '''a native full-frame aspect ratio of ~1.34:1'''. This is the aspect ratio of the vast majority of 16mm prints encountered in exhibition settings today. Exceptions are usually encountered when projecting a print of a film that has been reduced to 16mm from a 35mm print, or when projecting certain experimental or artists' films. The ~1.34:1 full-frame aspect ratio is the same for sound prints and for silent prints. <gallery widths...")
