I had a good experience with my 20-week scan in the public hospital and was at Pamela Youde in Chai Wan. The technician took her time and did the full structural scan. We had already gone to the private doctor at 16 weeks and he was 90% sure that our baby is a girl. The 20-week public hospital scan confirmed we are having a girl. The technician gave us a nice little photo print-out of our baby's profile but this is not standard because she smiled at us and said, "Shhh...and don't tell the other ladies in the waiting room." She was the happiest person I've ever encountered in the public hospital system in HK and even cracked a little joke during the examination. I don't know how much luck you'll have getting a photo at your exam, however because the procedures aren't really standardized and it all depends on where you're going, who you see and what their mood is that day. If you really want a nice ultrasound photo from this scan, I would skip the public hospital and schedule one with a private doctor--many of them can provide you with a disc with short video clips and photos on it but it will cost you quite a bit more, I think.
