I used Babybond and they didn't get any decent pictures so a waste of £300 in all, and the people in before and two couples after got the same dissapointing result - we did a lot of toing and froing into the room, drinking eating, walking etc trying to get our babies to move etc to no avail - but maybe you will be lucky there are some great 4d pictures out there so it must work fine for some people
we were also told to take our own music with us but they didn't bother said their whale music would be more atnospheric - I have to watch the dvd with the sound off!!!
we have this 20mn dvd now with a lot of placenta and the 2d bits between the 4d digitisation are by far the best thing on it so maybe get another of those if you can from babybond or similiar, though to be honest soon you will have a wee baby to take tonnes of pictures of and the scan will hardly ever be looked at again so save your pennies and get some cool professional photos of your newborn - or a hand/foot cast - those are cool I hold my wee ones 4 week hand and foot now and they are so realistic and sweet, he is now double their size and I am definitely going to get some more done when he is a year old - we did a clay impression for 6 months and a hand print for 9 months. We also just did a family portrait sitting with my parents and got some really beautiful pictures - expensive though, so do shop around.
