I didn't have video at dd's birth and now I'm really glad... I have such a beautiful memory of the birth - vivid but kind of hazy. The real thing was more raw and I think would be painful for me to look at now.
There are a few photos, which I use when telling the story to illustrate what the birth center looked like, etc. But because I was hot at the end and birthed with no clothes on, they aren't photos which most people would feel comfortable seeing. I'm glad to have the, though. Next time I would do black & white.
Anyway, I read the part in Birthing from Within about birth videos after dd was born... and I realized that it was true at least for me that without video I had a special memory of my own perspective, and I think the sight of myself "from without" could have been traumatic to watch. Also with other events, like our wedding, for which we have a video, I've noticed that starts to take over my own memories until my only images of the event are those from the video.
