When I'm on a FaceTime video call, there's a camera button.
When I press the FaceTime camera button to take a photo, I get the message:
FaceTime Photos must be enabled on both devices to use this feature.
What is FaceTime Photos? How can I enable this feature?
You can add another email address for FaceTime in your iPad:
This will allow you to call your iPad uniquely with this id.
Similarly, you can add another email address to your MacBook Pro's Facetime:
Yes - this technology seems to be driven by your contact card info stored by calling party. If calling party has info for you and someone else in same contact card, then both phones will ring for FaceTime even if not same Apple ID.
In our case, we had friend who had stored my number and husband's number (not email) under my contact card. Both our phones would ring when friend tried to FaceTime me, even though husband and I have separate Apple IDs and caller never selected the other number.
Solved it by having calling friend remove the additional phone number from my contact card on his machine.

This camera button is the FaceTime Live Photos feature.
iOS > Settings > FaceTime > FaceTime Live Photos
In addition to the Settings toggle, there is a minimum OS requirement. I got the same error message when FaceTiming with an older macOS computer.
