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 allows you to shoot
images in which, for example, a car’s taillights seem to trail
off behind.
