I have both the OC 2 and 3 cords , but neither will allow 2 flashes . What I want to do is fire 2 flashes at same time , but no line of sight .
I want a cord that I can connect another cord to .
Thinking about 2 flashes , I already have a 380 and a 580 II and want to fire at same time .
What I am trying to do is make a time lapse and want to keep light the same for day and night . One shot an hour over at least 3 days to maybe a week .
I posted for a formula to figure out what setting with ND 3 BUT right person has not seen it
I also posted in flash forum .
Also anyone know of a timer that will turn on a light for 5 minutes every hour ?
