The screen is hardware. It&#x27;s wired to the camera. Both are independently addressable via software. Making a small screen consisting of only a single LED and moving it close to the camera doesn&#x27;t change that...so long as the two are hardwired and one or both are programmable, there&#x27;s no certainty.<p>Short of removing the camera from the device, physical disconnection is the next best thing. To put it another way, a camera can shoot at 1&#x2F;2000 of a second. That&#x27;s quick enough that a person will miss the blink of an LED even if it&#x27;s activated 10 times as long as the shutter is open. So any indicator is going to have to programmed to show future and&#x2F;or past events to conform to the human time frame...or as some might say is the case with all things photographic, it has to be programmed to tell a lie to be useful. It&#x27;s just a matter of whose lies it tells.
