Taking Childbirth Photos

I've had a lot of questions about what camera and settings to use when taking childbirth photographs.  I used a Nikon D700 to take these.  The quality of photographs taken at higher ISO's is much improved over my previous Nikon camera.  I was able to use ISO's of 1600, 2500, even 3200 with good image quality.  Usually the hospital staff will ask that flash not be used.  With a camera like the D700 you can use high enough ISO settings that flash is not necessary.   I used shutter speed priority set on 60 so that I could hand hold.  It also helped that I have a f/2.8 lens.
