I want to set up a shot where I have a couple standing still whilst I write a word with sparklers next to them. The couple is frozen by the flash and the word is clear.
I have tried this with the 580ex set to rear sync and this works fine but can I do this using the 430ex II as well as a second off camera flash?
So the set up would be 580ex on camera and 430ex II off camera. How do I fire both flashes in rear sync mode? The only way I can get the 430 to fire is when I set the 580 to be the master the 430 to be the slave but then I don't have the option to use rear sync on either flash guns.
Does anyone no the best set up using these flash guns and camera to freeze the couple but capture the writing with a long exposure?
