I'm very new to photography and I'm looking at some videos about the system and I'm like "So the flashes communicate wirelessly instead of having to sense light bouncing from somewhere." I understand that that is a very good way to get them to flash without cables, smart for sure.
But is this "new" wireless technology so revolutionary? I don't get why it's taken this long. Please help me understand.
I have some background in hardware and electrical engineering (part of my studies at University) but I'm a software engineer by trade. So I'm somewhat aware of current technology.
The only problem I can see with why it has taken this long is the problem of latency, which they seem to have nailed.
