It could be a reflection. However, everything around the area is dark. So it probably isn't a reflection. Is there a problem with the camera in the one picture? You see spots in so many pictures, where the photographer doesn't clean the lens. A photographer can also turn on filters or not put them on if he/she has a good camera. For example, "red eye" for a blonde. Cheap cameras don't help. As for the other case, this could easily be a piercing. She does have a piercing in her belly button and she is wearing earrings. So it definitely can be the case that she has a piercing in her clit hood or on the side of her pussy lips. She is prone to have body piercings. However, in order to prove that you need to see more pictures from that same gallery. One picture cannot do anything. As for the unknown photographer in post # 1, it shows what looks to be a piercing. Could he/she be using a inadequate cheap camera? Although, the caveat here that is present, you also cannot prove that she has a piercing in this one picture. You need to see other pictures from the photo gallery. Are there any other pictures from that gallery around? And ones that clearly expose her pussy?
As for other pictures of her, piercings can stay in or she can take them out. She doesn't wear them all the time. That makes it really hard to judge. So to show her in a J. Stephen Hicks Digital Desire picture gallery (without the piercing) and a Woody (aka Rascal Dog) picture in a Foxes picture gallery (without the piercing) makes no sense. You cannot compare or contrast this between those well known photographers as they show the same thing. Pictures that don't show a piercing.
That's all I'll say about this. The end.
