Flash- Second-Curtain Sync question, Sir/ Madam.

[surapon]

Dear Teachers and Friends.
Yes, Every time that I  do not have a complete understanding of Photography Technique, I must ask you, my dear teachers and my dear Friends---And I get all the answers that I need to improve my Photographic skill.
In my Life ( Photography Hobby) I just use / Set up The Second-Curtain Sync. Flash a few times, To Create  the Light Trail following the Car( for the back ground) in the night time , with my wife  at the main subject, When I use super slow  speed shutter, and the flash fire right before the shutter closes.
The Question is:
Sir/ Madam, Do you  use the Flash Second-Curtain Sync with any  type of  photography else?---Such as the Portrait Photography,  Candid Photography or Artistic Photography ?
Thanks you Sir/ Madam.
Have a good Saturday Night.

If you're shooting in the rain with a flash, second-curtain will make the rain look like it going down.  First-curtain will make it look like it is going up!
