Nessie, the Loch Ness Monster has been seen, photographed, and videotaped on a number of
occasions, but what is the best photographic evidence of Nessie?
I am not taking into account videos, only photos.
I think the best photographic evidence of Nessie is the 1975 underwater photo of Nessie, taken by Robert Rines. The photo shows, quite clearly, indeed, a plesiosaur-like creature. With flippers, a long neck, and a big head, this photo is very unique.
Ogopogo has also been seen, photographed, and videotaped on a number of occasions, but not as much as Nessie, though.
The best photographic evidence for Ogopogo is most likely the Francey/Gaal photo taken in 1980.
And, undoubtedly, the best photographic evidence for Champ is the Sandra Mansi photograph taken in 1977!
