For me, I look back on pictures and tapes of my childhood with joy. I'm glad my parents recorded those things and I can go back and see how things were when I was 3 or 8 or 12.
"Wait wait, do that again so I can get a picture of it! No no you were over here, don't face this way do what you were doing before just pretend I'm not here. What's wrong, you were having fun a minute ago stop pouting!"
Camera people can be really obnoxious like this, particularly to young children who haven't yet learned the value in humoring their parents. I always hated it when my mother got out the camera. If she had stood back and taken pictures without trying to arrange everything for the 'perfect' pictures it wouldn't have been such an issue. But that's not how it ever went.
Five year olds now have practiced photo poses and a ready-to-go fake smile, because every goddamn day is a photoshoot.
Not the person you are replying to, but I can explain to you how it was "taking me out of the flow", because I have the exact same feeling about my mother and taking pictures.
If it was just her taking pictures while I was doing something like playing in the yard, that wouldn't be an issue. However, it was never just this. It was always "ok ok, hold up, one sec, can you stand over there to the right and look in this direction and smile?" whenever we went somewhere that was supposed to be a fun experience that wasn't a part of the daily routine. As a kid, you can imagine, stopping doing whatever fun thing I was doing just to awkwardly pose for a photo I don't care about in the slightest for a few mins, it was an aggravating and not a fun experience.
I actually would not have minded at all if she took pictures of me while i was doing something without interrupting and stopping everything. To this day, I find photos of me (and just in general) taken "naturally" (without stopping things and everyone posing intentionally) to be the best all around. They just look real and looking back at them makes the memories of that moment flow back into my head much stronger.
100% my impression too. Photos where no one is trying to "pose" are the best (with few exceptions). But my significant other disagrees. She feels there's no point in such photos. We've agreed to leave it at that.
In addition, I gather a sense of happiness curating photos a few months after the photos were taken. I tend to remember the details of such events in a lot more detail and for much longer. I remember much less looking at a picture of us posing for a scenic background as compared to a picture of just her, in the moment, doing something.
I now enjoy capturing 20 second videos of me and family doing whatever, with no one trying to pose, they just look at me with the phone and smile or wave. The background conversations captured in them string together a lot of precious moments and memories.
