Introducing the Shirley-Wellard Type C Universal Cassette. Instructions for loading and using the universal cassette and Instructions for adjusting.

The vast majority of cassettes for 35mm cameras can be divided into two types, the sort with a fixed velvet-lip light trap and the labyrinthine type.

At their most basic, paper grades could hardly be easier to understand or to master. Paper grades range from 00 (very soft) to 5 (very hard).

It is amusing that today, 120 film is regarded as a professional medium that is difficult to handle. After all, for decades it was the amateur standard for snapshots, used without a second thought by even the most fumble-fingered.

For most practical purposes, ‘medium format’ can be taken as synonymous with 120/220 roll film, though another way to define it is by what it is not: it is bigger than 35mm, and is therefore not ‘miniature’ but it is smaller than 9x12cm or 4×5 inch, and therefore not ‘large format’.
