I voted take pix. With dd1, I allowed NO cameras at all until about an hour after birth - everything cleaned up, etc. Now I am so sad that we have no pix of the first time we held her, just after she was born.
With dd2, the midwife's assistant took some GREAT pix! Truly fantastic. I treasure them. Some were too graphic but some were perfectly PG - there is a two page spread with these in her photo album and everyone from my brother to my husband's friends have seen it and I am not the least bit embarrassed - they are in very good taste. Nothing "shows" at all (she shot from the side - you'd have to see them but it is fine).
Dd3, the second midwife took some pix. With dd2 and dd3 we used B & W film - YOU MUST USE BLACK AND WHITE FILM!!!!! It captures the moment so perfectly and none of the blood shows! I feel very strongly that you should take pix (you can always hide them away so no one ever sees them - or whatever but you can never get them back if you don't have them taken). You cannot regret taking them IMO.
Yes, there are two kinds of B & W film. I have used both. We used the better/more expensive kind with dd2's birth. Had to be developed at a photo place and I assume someone definitely saw them. We used the other (it is called C-41) with dd3's birth. C41 can be developed anywhere. We used Costco one hour. I don't think anyone saw them - they are so busy there.... The machine spit them out, someone tossed them into an envelope, gave us our negatives and away we went. I was right there watching them come out of the machine. They may not be quite as high quality as the film/pix from dd2's birth but they are still good.
So I vote take pix with B & W film!
