Scary picture, but there is no context at yahoo.com on how this was generated. It just looks like a black and white negative.
No, it’s not a negative. If it was, Her Highness’s face would be black instead of white.
I think the caption explained it - it’s shot through the viewfinder of a video camera.
It looks to me like a picture of her in the viewfinder of a video camera. There’s a small B&W screen in the eyepiece of those.
The image is either processed for "night vision" or somehow solarized (which gives part of a positive and a negative image)
