The Norwegian Epic is the first ship I sailed on that uses facial recognition for photographs and; Wow, what a difference it makes!
When you board the ship they take your photo, like they do for most ships these days. After that whenever you take a photo the photo software uses facial recognition to identify you in photos. And it does a great job at it!
The photo area of the ship has triangular pillars with a binder for each cabin, photos are placed in your binder. No more searching through walls of people in the same photo setting as you.
Ok, there was a wall of photos where they weren't able to identify someone, but it was a small wall and I know that every photo I took ended up in my binder.
They do also scan room cards when going to the professional photographers, which I'm sure does help the process, but the mobile photographers did not do this. That is what made this so amazing.
In addition to the binders they also have computer screens where you can view and order your photos. If there is a bad photo, you can say that it's not you and it magically goes away. You just have to be careful that you don't do that to a good photo, I'm not sure if there is a way to get it back. You can also order prints through the computers.
From what I hear the Disney Dream may have similar technology, I hope it does. It's really fantastic and makes the photo buying experience soooo much better on cruise ships!
