Loading Retinette Cassettes
The Retinette cassette consists of a flanged centre spool which is in a one-piece shell; the film leaves the shell by a
light-trapped slot. The centre spool can be removed from the shell by lifting either top or bottom of the cassette
according to the construction of the particular make of cassette. Most of the cassettes of the daylight loading films
are intended by their makers to be used once only. However, they can be re-loaded quite a few times -- if handled
carefully.
WINDING AND TRIMMING FILM

centre spool of the cassette) with a standard trimming template.
2: Trimming of the curved cut with a standard trimming template.
