But did you run the code, THEN shine the light and set to hold? Or did you set it to hold then shine the light & run the code?
Im trying to understand how this is done, because I dont see a way you can change that setting while the code is running. Unless I'm completely missing something here. Is this done in labview? The camera settings in the browser?

I should be good from here, thanks everyone. I wont be able to try it until we unbag on friday. I'll try this with the red first, and if it doesn't work and the green one is here in time, I'll switch over.
