Section 2 - Operation
Exposure Modes (Shutter and Light Interception Blades)
The Miniportrait Model 203 has two exposure modes: single (half- frame) exposure
allowing two different portraits on a single sheet of film, and dual exposure allowing a
pair of identical portraits on a sheet of film.
Accordingly, as shown in Figure 3 the shape of the Shutter Blade (A) and Light
Interception Blade (B) in the 203 are different from those in the Miniportrait 403.
Shutter charging and recharging functions of the 203 and 403 are, however, the same.
(For a description of these functions, see Section 2 of the 403 Repair Manual).
