For example, if the number of ashes is 10 and the ring
frequency is 5 Hz, the shutter speed should be at least 2
seconds.
• To avoid overheating and deteriorating the ash head,
do not use stroboscopic ash more than 10 times in
succession
• After 10 times, allow the speedlight to rest for at least 15
minutes. If you try to use the stroboscopic ash more than
10 times in succession, the ring might stop automatically
to protect the ash head. If this happens, allow at least 15
minutes’ rest for the speedlight
• Stroboscopic ash is most effective with a highly reective
subject against a dark background
• Using a tripod and a remote control is recommended.
• A ash output of 1/1 and 1/2 cannot be set for stroboscopic
ash
• Stroboscopic ash can be used with“buLb”
• If the number of ashes is displayed as “--”, the ring
will continue until the shutter closes or the battery is
exhausted. The number of ashes will be limited as shown
by the following table.
