dropControllerV4 with a single valve and two flash. This is as basic as it gets.
The dropControllerV4 is fairly straight forward to set up:
dropControllerV4 with camera and flash connected.
On the back the valve connected to Valve Port 1 and power in plugged into the PWR Port. Here I am using a 24V power supply with a 24V Shako valve.
Two extension leads are provided to make the shutter and flash leads longer if required.
Multiple flash can be connected to the FT Port. A simple way to add more is to use Y Cables/headphone splitter leads. Here two flash are connected together using a Y cable.
Y cables can be piggy backed to add more flash.
Once you start using multiple flash, a wireless system is a more convenient option. Here is my Yongnuo set.
How to trigger the flash
There are two main ways of using flash:
1 – triggered by the camera
2 – triggered by the dropController
Either way can work for drop photography but I always recommend connecting the flash to the dropController and using the flash trigger function in the app. Allowing the dropController to trigger the flash allows for extremely accurate and precise trigger times and means there are no issues with shutter lag or shutter syncs.
