| Definition: | The playback direction of the reel/roll. |
| Purpose: | Indicates the wind of the roll/reel so that it can be read and reproduced correctly, on either the base or emulsion side. |
| Relationship: | This element is dependent on Media Type. Each media occurrence of the archival materials must have a media type specified to create Wind. |
| Guidance: |
Choose the correct term from the Wind Authority List. For exposed and processed film that has an image: "B Wind" reads correctly when the image is viewed through the base. (The film base is the shiny side of the film.) "A Wind" reads correctly when reading the image directly off the emulsion. (The emulsion side is the coated, dull, less reflective side of the film.) |
