Which is Which

A shortend is the unexposed remainder of roll in a magazine that is clipped and placed back in a can for later use. They vary is size from 100 to 990 feet for 35mm. Shortends are the least expensive form of motion picture film stock.

A recan is film that was loaded into a magazine but not even partially shot. Usually, a roll of film that was opened in a black bag or film tent, but not used.

Factory-sealed film is exactly as if you purchased it directly from the manufacturer.

Film Testing Procedures and Storage

Labs use D-min readings (essentially density number readings) to detect each individual stock's relative age and quality. Each developed negative splice is also inspected for signs of fogging. Fogging occurs from light leaks, most commonly attributed to camera "doors" not being taped. Fogging is detectable on negative when there are light streaks or as most often the case, when sprocket holes on the edge of the negative are repeated as an actual image. All fogged film should be immediately discarded to recycling bins.

Film does degrade over time and is treated as perishable. It's emulson compound can often thin through aging producing results if used that are unpredictable. All film should therefore be properly refridgerated. Recommended storage temperature should be approximately 45 to 55 degrees farenheit.

With respect to shipping, particularly cross-border, it is recommended that all outside packaging be affixed with "DO NOT X-RAY" labels. Most major carriers are aware of the sensitive nature of film shipments.
