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??
