Here is a comment from the photographer herself (Vanessa Bristow):
To all of you DOUBTING THOMAS’ out there who distrust the originality of this photograph, it is NOT Photoshopped.
I was in the local communal lands looking for my lost Dalmatian dog, and I stopped to ask his mother if she had seen it. While I was talking to her, her son, who was playing with his siblings and friends nearby, caught my eye. I asked her if I could photograph him, and this is the first picture that I took of him – it was possibly his first interaction up close with a white person, and his fascination in me, or in the camera, is plainly evident.
I took a few photos of him at the time, and a few more later on a follow-up. An ophthalmologist friend had this to say about his unusual eyes,
"The picture of the little boy with the blue eyes and dark skin probably represents Ocular Albinism or Nettleship-Falls albinism, or Juvenile uveitis. Both conditions cause the pigment of the iris to be less dense."
