Image orientation appears in many forms. They are filmed in either the positive or negative, with varying image lengths and sizes. There have contrasting image density, possibly due to film being degraded, or the result of inconsistencies in the original development process. The reduction ratio or aspect ratio may also differ technically. 35mm film was commonly reduced 12-16x, while 16mm usually ranges from 20 to 48x.
The 16mm role cartridge which was a popular early type of film. It was kept in a sealed cartridge to protect it. The roll film cartridges may not have been perfect for scanning initially.
