I mean, she was definitely using her phone while driving at 70mph. Does it really matter whether or not she was taking a pic or sending a text? It’s still incredibly dangerous.
No, it was all safe. She took the picture from the passenger seat while OP was sleeping.
I feel like a lot of people have never done a long road trip where you’re driving hundreds of miles through the night. Taking your phone out and snapping a pic isn’t a huge deal IMO. I certainly don’t pull over to change my radio and taking a picture is arguably easier than that.

I would argue it is harder and more dangerous. With the phone you need to unlock it, select camera app, then make sure it focuses (which doesn’t work that great at night, you have to look at the screen, tap on the area you want to focus), second thing is that due to low light conditions to avoid blurring you need to be perfectly still (which is hard to do in a moving car, especially if you are driving), this makes you check the picture then retry, then check again etc.
You likely could spend even a minute looking at the screen to make sure you got a good picture. Each time you switch your eyes need to adjust their focus which also takes a second, but that it is insignificant to the rest.
BTW: even changing the radio station takes enough attention to cause accidents (that’s why they started adding controls on the wheel), but taking a picture (especially at night) is way more dangerous.
