Flash shooting
2nd curtain (rear curtain) #SLOW2
With 2nd curtain, the flash fires just before the shutter closes. Changing the
flash timing can create interesting effects in your picture, such as expressing
the movement of a car by showing the tail-lights streaming backwards. The
slower the shutter speed, the better the effects turn out.
The slowest possible shutter speed depends on the shooting mode:
M mode
P, A, S, m mode : 4 sec.
When the shutter speed is set to 4 sec.

1st curtain with red-eye reduction HSLOW1
This mode is for when you want to use slow synchronization, yet also reduce
the red-eye phenomenon. For instance, when shooting a person against a
brightly lit night background. A normal flash might make the person's eyes
red, but 1st curtain with red-eye reduction lets you capture the background
correctly and reduce the red-eye phenomenon at the same time. 2nd curtain
with red-eye reduction is not available.
