Boris Eldagsen, distinguished with the Sony World Award for the black and white image of two women of different generations, has put the prestigious award in a serious dilemma. "AI and photography should not compete with each other in an award like this," the German artist explained.

"For some artists, it's a new tool, maybe a new category of art," BBC technology expert says.
