Radio transmission or optical transmission?

[Ravinder]

Hi guys

Just setting up my Godox AD600B flash for a wee shoot tomorrow for a friend. I’ve never used it before so just trying to familiarise myself with it.

I have the option to set it to radio transmission or optical transmission. Can someone please tell me the difference and where I should have it set?

Many thanks,

Ravinder

Presumably you’re using an appropriate transmitter, what transmission method does it use?

 

[Ravinder]

I’m using Godox XPro-N trigger.

Radio can work blind… that means that the transmitter
must not have "visual contact" with the receiver. Radio
has a much greater radius of operation and a more re-
liable function.

Optical is a light signal that MUST be seen by the recei-
ver and is often failing in daylight conditions.

Given the choice, I'd go radio… all the way.

Then you’ve bought a radio trigger.

That’s great, thank you all.
