Dude, no.

I get annoyed as hell with my very sweet husband for taking a handful of pictures when we are out and about. It can actually ruin the experience if it means constantly pressing pause on whatever you are doing to "capture the moment" or whatever.

You sound a lot nicer than me, but I would straight up say no. I would probably prepare her for the inevitable no, by in advance telling her that I plan to just enjoy the event and intend to take a break from photography duty. I would very quickly establish some boundaries about when I would even consider taking pictures and how many I would take, and she'd be lucky if that meant even 1 photo op the whole day.

This sounds completely insufferable.
