Slave mode flashes

Work in slave mode

— the ability to work as a flash in slave mode is useful for creating a system of several flashes (for example, in studios): without this function, the device cannot be connected to a control (master) flash and ensure synchronized firing. On the other hand, this feature adds some cost; therefore, if you do not plan to use combined systems, there is no point in specifically looking for a flash with support for slave mode.
