You can't be too careful when you see a Nessie photograph these days. I stumbled upon this picture at the facebook page of an enthusiast of El Nahuelito, the monster of Lake Nahuel Huapi. The title of the picture is "Loch Ness, Old Photograph".
There is an obvious suggestion of a long neck and a hump in the middle of the picture. Perhaps a genuine picture but then I thought I had seen this photo before. A look at my own blog revealed all.
This is one of my trap camera pictures shown at this previous posting. I wouldn't call it an "old photograph" either as you can tell from the timestamp: 13th May 2012! In fact, my posting went up on the 7th June and the doctored image was uploaded to Facebook 9 days later!
Sadly, the Internet is replete with fake images of lake monsters and sea serpents accomplished with models or photoshop. In fact, I am sure they outnumber the accepted images by a wide margin. Perhaps the owner of the Facebook page would enlighten us as to where he/she obtained this image.
