Memo Holder
The back cover of this camera is provided with a memo holder. Once you have loaded the film and set the ASA, it is very useful to tear off the end of the film box and insert it into this memo holder as a constant reminder of the type of film in use. Add other information as you like.
The Basics of Exposure
This section contains some terms and definitions which will be used throughout this instruction booklet.
The amount of exposure is a matter not only of the amount of light allowed to strike the film but also of the amount of time the light is allowed to strike the film. The camera has two mechanisms to control exposure, the diaphragm and the shutter. The diaphragm consists of blades which open and close to certain size openings called apertures. The size of the aperture determines the amount of light which will fall on the film. The various size apertures are indicated by a set series of numbers called f/stops or f/numbers. Each f/stop represents some amount of light that is allowed to pass through the lens. The smaller numbers are called large f/stops while the larger numbers are called small f/stops. This is because the larger numbers represent smaller apertures and allow less light to pass
