Anon viewers are two types, mainly those are visitors and therefor non-members or the members not logged into Ipernity at the time of their visit.

I don't know but I suppose that most "anonymous" views are not from visitors or logged out users but from users who have determined in their account settings that they don't want other users to be notified when they visit their photos.

I have to admit that I have chosen this setting, too. So my visits to your (and everyboy else's) photos will be shown as anonymous visits. But that doesn't mean that they are less meaningful. :-) It is simply a data protection concern: I would feel watched if every single page visit by me were notified to the photo owners. If I like a photo or find it interesting and feel that the photo owner should know about my visit I can fave or comment the photo.

So there are different perspectives from photo owners and photo viewers: As a photo owner I sometimes wished, too, that I could identify each visitor. But from the persepctive as photo viewer I feel more comfortable if I can determine whether the photo owner is informed about my visit or not.
