I hope this will be left, as I would like to have the minds of the regulars here have a go at it. I have this speedlite problem.

I feel that I have a fairly analytical mind, and can generally work through most problems. This one has no apparent logic behind it, and if it wasn't happening to me, I would say is impossible.
Cheers, Neil

Did some googling, I know nothing about flash period. It may be your bright ambient I see in your shots. Try same location at night or when darker.

http://photo.stackexchange.com/questions/52818/strobes-that-will-trigger-from-on-camera-flash

The drawbacks are the usual ones with any optical triggering system: range, line-of-sight, and being overpowered outdoors. The sensor must "see" the light signal. If there is anything blocking the master signal from the sensor panel, the signal won't get through, and it won't fire. Outside in bright sunlight, the signal might be overpowered and not register highly enough over the ambient light, and the signal is lost. And if the master signal is very far away, again, the signal might be lost. These triggers work best in studio conditions, where there are bounce surfaces to relay the signal if there's no direct line of sight, and where the master flash pulse will be considerably brighter than the ambient lighting.

Thank's for the try Frank2013. The trigger speedlite is enough to, during the middle of the day, throw a shadow of the feeder 20 ft away onto a sheet hung 6 - 8 ft behind it. In my tests we're talking 5 - 10 ft.

Not trying to argue and as I said I know nothing, but the point was that the sensor has to see the light. If the ambient light is too bright even if you can cast a shadow it might not be bright enough to overcome the light the sensor is sensing. Best I can due without further research, I'll leave you to it, good luck. Just wanted to make sure you understand what was being said, I'm sure you do.

You may be right. But would it hold when the trigger/receptor are reversed. The receptor inside should see the bright flash ouside??

I'm starting to think you have hit it. Did some more tries in the reversed positions, and getting some different results. Things may hinge on the charge state of the batteries. Back to the "drawing table". Thank you for the input.

I'll go back to your earlier statement....if it wasn't happening to me.laugh

Edit: I just got this typed up....darn. Should be getting dark in a couple hours so you can test some more.

Batteries could be a key element also, good call.

The answer...ambient light. The sun has now left the entire viewing area, leaving all in shadow. The "slave" now responds to the "master". Thank you all who responded, and took the time to help
Cheers, Neil

Good to know, thanks for sharing the result.

If ever the slave does not respond to this master they get a damn good whipping! Only way to keep em in their place.
Feed one to the lions occasionally to keep the rest on their toes is not a bad idea either.

Thank's for the helpful advice Billy. I you had been online earlier I could have had the solution a whole lot sooner. As it was I had to wait for Texas Frank.
