Energy Control
With the dial BRACKET (15) the total energy can, irrespective
of the energy distribution, be reduced to 1/4, i.e. two f-stops.
The flash duration, recycling and colour temperature is affect-
ed by using the dial BRACKET. When using the bracketing dial
(15) to reduce the energy you need to dump excess energy by
pushing down the test button (5). To obtain the shortest
possible flash duration use the position max and reduce energy
by using the energy switches.
Bracketing
The BRACKET DIAL can also be used to obtain alternative
exposures - "bracketing".
1. Turn the dial to -1. Find your correct f-stop with your flash
meter. Make the first exposure.
2. Turn the dial to max. The power increases to an overexposure
of one f-stop . Make the second exposure.
3. Turn the dial to -2 energy. Press the test button (5). After
recharging the power is decreased to an underexposure of one
f-stop.
4. Now make the third exposure.
This procedure results in three different exposures. One is "cor-
rect", one is overexposed by one f-stop and one is underexposed
by one f-stop. There are three different exposures without any
change in lighting or depth of field.
It is of course possible to choose only1/4 or 1/2 of an f-stop
"bracketing". The distance between marks is 1/4 of an f-stop.
