Prince Harry, a keen amateur photographer, has shared a selection of images from a trip to his charity project Sentebale in Lesotho last week.
The three black and white shots taken by the 30-year-old prince show groups of children and a man in traditional dress at his charity, which supports disadvantaged children - many of them Aids orphans or who have the disease themselves.
"I have always enjoyed photography and the challenges that come with trying to capture the perfect shot, although privately I don't take many photos," Prince Harry said.
"The best photos I have are in my head - I have some very special memories, mostly from Africa. But on this visit, I had the time and opportunity to be on the other side of the camera and take some photos in the stunning country of Lesotho for my charity Sentebale."
The Prince also posed for a series of shots, including one where he and a group of children posed in Santa hats.
Commenting on the photograph, Harry said: "Festive cheer! Despite it being 32 degrees, someone gave out Christmas hats and inevitably one found its way onto my head.
All the children, orphaned for one reason or another, absolutely loved the hats and balloons. We even managed to squeeze a hat onto Prince Seeiso's head! Again, so nice to see the place so well looked after."
In another photograph, he is pictured swinging a young boy in the air.
Explaining how the shot was taken with the help of a young blind girl, he wrote: "Wow, what a welcome we got! There were 40 over-energetic children using us as climbing frames, water fights, and a lot of laughs.
"The boy flying is Lerato, a three-year-old who was abandoned at birth. The photo was taken by three-year-old Karabo, who is blind.
"She heard the clicks, went to the camera and, with a little bit of help on direction, shot this great photo."
Sentebale is in the process of building a major new project, its Mamohato Children's Centre, which will provide emotional and psychological support to children currently affected by HIV and Aids.
Some really outgoing chatty kids, others slightly overwhelmed, but all with huge smiles.
The Prince said: "These are children who have never had the chance to talk about their illness, and who had no idea that they were one of so many in their age group."
"This confirmed to me again that what we're doing is going to change thousands of children's lives, and hopefully save a generation," the prince said.
