Just like to find out when should I use slow sync flash.
My C2040Z offers 2 kind of slow sync flash:
1. Fires flash during first half of the time the shutter is open
2. Fires the flash during the second half and fires a preflash b4 the main flash fires.
When I normally took group pictures of my friends and colleagues, my C2040Z flash will often ruined the picture with a whitish outcast. So will a slow sync flash resolve this problem? Or is it not even suitable for taking potraits shots?
Thanks for any assistance
