A
Interval Timer Photography
Choose an interval longer than the time needed to take the selected
number of shots and, if you are using a flash, the time needed for the
flash to charge. If the interval is too short, the number of photos taken
may be less than the total listed in Step 2 (the number of intervals
multiplied by the number of shots per interval) or the flash may fire at
less than the power needed for full exposure. Flash output may also fall
below the desired level if more than one shot is taken per interval.
Interval timer photography can not be combined with long time-
exposures (bulb or time photography, 0 138) or time-lapse movies
(0 74) and is not available in live view (0 44, 59) or when Record
movies is selected for Custom Setting g1 (Custom control
assignment) > Shutter-release button (0 360, 363). Note that
because the shutter speed, frame rate, and time needed to record
images may vary from one interval to the next, the time between the
end of one interval and the beginning of the next may vary. If shooting
can not proceed at current settings (for example, if a shutter speed of
A or % is currently selected in manual exposure mode, the interval
is zero, or the start time is in less than a minute), a warning will be
displayed in the monitor.
Interval timer shooting will pause when E (self-timer) is selected or if
the camera is turned off and then on again (when the camera is off,
batteries and memory cards can be replaced without ending interval
timer photography). Pausing shooting does not affect interval timer
settings.
