I realized that when I saw a picture of the hole from a different angle and immediately sent a retraction. It still looks weird, though.

Perhaps somebody tried to make certain >features of the photo stand out more (the dark line across the top of the >hole) by using Photoshop or some other enhancement program. I have seen similar, even heavier black lines appear around people in digital photos, forming an outline. I have no idea what caused it, but the photos were not manipulated or taken in any sort of odd way. Must be some artifact of digital photography under certain circumstances. Mark Minton
