Multiple exposure

Multiple exposure is only possible with 35 mm

film. To activate the multiple exposure mode,

press the <DOUBLE> button.

Pressing the <DOUBLE> button causes the

letter "D" to appear at the last digit of the

bottom line of the left display window.

The first exposure released with the <START>

button is not followed by data exposure nor by

power film advance. The letter “D” blinks. Only

after the second exposure released with the <START> button will data exposure and power film

advance by one frame take place.

You can release more than two exposures on the same frame, if you release the next exposure by

pressing the <DOUBLE> button instead of <START>, while "D" is blinking. Pressing the <DOUBLE>

button stops the blinking; the "D" symbol now is steady.

This can be repeated any number of times. To end the sequence, release an exposure by pressing the

<START> button while "D" is blinking. This last exposure is followed by data exposure and film

advance by one frame.

The function can be used for the following purposes:

Taking the same specimen detail with different illumination methods or fluorescence filters.

Overlay exposures of scales, marks or micrometer nets.

As the individual exposures add up in density, at least in places, each exposure should perhaps be

reduced in time, say, by one exposure increment (-1).

To cancel the multiple exposure mode, take one of the following actions:

Press the <DOUBLE> button again before releasing the first double/multiple exposure.

Press the <WIND> button to effect film advance (after an exposure made while "D" was on).
