Getting Started with
Macro Flash Photography
This chapter describes the preparations before starting
macro flash photography and the basic shooting
operations.
Cautions for firing continuous flash
To avoid degrading and damaging the flash unit due to
overheating, limit the continuous firing at full output to 20
times or less. After continuously firing the flash 20 times,
allow a rest time of at least 10 min.
If you fire the flash continuously 48 times and then fire the
flash again repeatedly at short intervals, the safety function
may activate and restrict flash firing. With flash firing
restriction, the firing interval is automatically set to approx.
8-20 sec. If this happens, allow a rest time of at least 25 min.
For details, see “Flash Firing Restrictions due to
Temperature Increase” on page 110.
Conditions of the subject greatly influence the exposure when
shooting close-ups. Therefore, it is recommended to shoot the
same subject with different exposures (p.40) and check the
exposure after shooting.
