For the test flash, set up the slave unit (with incorporated sensor) in the same manner as for the subsequent shot.

10.3 Maximum flash range indication

The maximum flash range is indicated on the LC display of the flash unit when in automatic A, ma- nual M or EASY mode. For correct indication in automatic A and manual M mode it is necessary to manually adapt the flash parameters - aperture, ISO and reflector status - to the corresponding ca- mera settings when a wide-angle diffuser or tele- photo attachment is being used or when working without an attachment (see Chapter 9).

The maximum flash range indication can be either in meters (m) or feet (ft) (see Chapter 11.2).

Maximum flash range indication in the auto flash mode A and EASY MODE

The LC display of the flash unit indicates the maxi- mum flash range. The indicated value relates to a factor of 25% of light reflection by the subject, which applies to most photographic situations.

Pronounced deviations from this reflection factor, e.g. highly reflective or poorly reflecting objects, can influence the maximum flash range of the flash unit.

When shooting pictures, be sure to observe the maximum flash range indicated on the flash unit’s LC display. The subject should be within approx.

40% to 70% of the indicated value to give the elec- tronic system sufficient leeway for compensation. The minimum flash-to-subject distance should not be less than 10% of the indicated value to avoid overexposure. Adaptation to the given photogra- phic situation is possible by changing the aperture

setting.￿

Maximum flash range indication in the manual flash mode M

The LC display of the flash unit indicates the dis- tance to be maintained for correct flash exposure of the subject. Adaptation to the given photogra- phic situation is achieved by changing the aper- ture setting and selecting between full light output and partial light output levels “P 1/1 to P 1/16” (see Chapter 9.5).
