Shooting Images at Set Intervals
(Intervalometer)

fixed-point observation of plants and blooming flowers. The shooting
interval time can be set from 1 to 60 minutes and 2 to 100 images can
be shot.
Mode Dial
1st-curtain
The flash fires right after the shutter opens, regardless of the shutter speed.
Usually, the 1st-curtain is used when shooting.
2nd-curtain
The flash fires right before the shutter closes. Compared with the 1st-curtain,
the flash fires later and this allows you to shoot images in which, for example, a
car's lights seem to trail off behind.
