Double Exposures?
Although this camera has a built-in double-exposure prevention, it is quite possible to take double-exposures, which can be quite effective. To accomplish this, follow these 7 simple steps below. It is assumed that the selection-knob between the two lenses of the camera is in Position "A".
1. Make the first exposure
2. Wind film (transports film and cocks the shutter)
3. Cover both lenses and release the shutter
4. Turn the selection-knob between the lenses from Position "A" to Position "B"
5. Wind film (transports film and cocks the shutter)
6. Turn the selection-knob between the lenses from Position "B" to Position "A"
7. Make the second exposure (the "Double Exposure")
