Rory, I think once you get your head around the whole thing, do your research and are so informed on everything, you get taken away with it all.
It's a very empowering thing to do. Funnily though, women were birthing at home only 70 years or so ago as a natural thing. Women in other countries do it everyday, and it's the norm.
Each to their own though :)
Rachel, get the photos. If you don't like them you can get rid of them, but you can't go back to take more !!! They don't have to be distasteful, not that I think any birth pics are. But I'm sure you know what I mean.
