Just wondering what the delay is like between taking photos. I have kids so during hectic moments I frantically click the shutter button to try and capture the best shot. This works with normal photos on iPhone brilliantly and I just choose the best shot. However with Live Photos recording 1.5 seconds after, do you have to wait that long before taking your next shot? Or is it able to take several Live Photos in quick succession and use the same 'buffered' shots to create them all?
