I was playing with this for a while today, I did a 1250X Hi-Res zoom and sharpened it quite a bit. I can see there's some sort of shape there but I can't see a woman at all, and with this enhancement you can see it's not one large form, on the left you see the grass in parts???
So I really don't know, but I can't Explain what the darkness is?? I would need the original unedited picture to try more.
