We had a lot of fun posing every night and finding backgrounds we liked. We ending up getting a couple of really nice photos of us. I never felt any pressure from the photographers. We found some better than others and went to them over again.
We also bought a photo of us getting off the ship. This is where my trouble started. I didn't realize that those pictures we not standard sizes and if Carnival was selling frames for those I didn't see them or wasn't paying any attention.
My happy solution!! I found a floating frame and centered the photo on it. Then I went over to the scrapbooking section and found some cruise themed stickers and made a cute border all around.
So make sure you get the right sized frame on board or you can try what I did.
