I don’t think it is photoshopped, but I do think it is not that hard to attach something to an toy underwater submarine, have it pulled across the water, and make a picture. That is how the 1933 Nessie picture was made, no? In that case, he is not even lying when he says that his sources comfirm that the picture is " a real picture of something moving through the water" .
Also, that second picture shows the man to be way, way too attentionseeking. Anyone who wears such a beard, such a tan and such a captains cap so un-ironically is trying to set us up.
Why would anybody go through the effort of photoshopping a dark, nondescript object bobbing about the surface of the water? If they were going to photoshop something, at least make it look interesting.
Trace: You know Jenny?
Mum: Jenny Jenny?
Trace: No, Microwave Jenny. She says the trick is to make them look real, but not too real, just real enough to know they’re fake.
A friend of mine has told me about staying in a scout camp by Loch Ness when he was a boy. Neither he nor any of the other kids saw any trace of Nessie, something that he attributed to being too young to drink whisky at the time.
