It's from Ryan at the HalfThrottle Youtube channel.
While travelling in Panama, he wanted to take some photos of the locals, but wanted to share the photos with them as well - many of them, after all, did not have any family snaps of their own.
He took along some equipment to develop the photos on the day, and shared copies with those individuals he photographed.
He said, "With this video I hope to inspire other travelers to get out and meet the people who really live in the country the visit. Wander around, get lost, make some friends. Days like this will become the very best memories of your vacation."
The video is below. You can also watch a bit more of the photo sharing event on a separate video, here.
