UK's Princess Catherine says she edited official family photo, apologises for confusion caused

Britain's Princess Catherine has apologised for the confusion she caused after releasing an edited image of herself with her three children to celebrate Mother's Day in the UK. It was the first photo of the Princess of Wales distributed by Kensington Palace since she underwent abdominal surgery in January. The princess said the image was the result of an experiment with editing. The British royal has not been seen in public since Christmas, and the picture has raised questions on her health.
