I saw a show on the Loch Ness monster some time ago that pretty much debunked the four famous images of the supposed monster taken by Robert Rines. I
really wish I could recall which show it was.
The camera that was used to take these pictures was supposed to be in a fixed position, but apparently it wasn't. Perhaps the camera came loose, but
it seems that it ended up tumbling around in the water, snapping pictures in random directions (the program showed one photo from the expedition where
the camera snapped a picture of the bottom of the boat).
The "nessie standing on bottom of lake" photo shown in this thread is possibly the image of a sunken tree on the bottom of the lake.
The famous 'flipper' photograph is not what it seems, either. The original image (was apparently enchanced. Twice. The original was first enhanced
by NASA's JPL, then apparently it was touched up once again by artist that worked for the magazine that first published the images. So you go from
vague, possible image of the lake bed to 'diamond-shaped plesiosaur flipper'. Compare the two (original on top, enhanced on bottom)
Then we have the third famous image from the expedition, the one that always creeped me out: the "gargoyle head" image.
Supposedly an image of the head of the creature. However, if you rotate it, it appears to be nothing more than a rotting stump. In the show I saw,
they even claimed that they went back to the exact spot where this image was taken and found a stump on the bottom that looked very much like this
So, are these images really of a monster living in the lake, or are they just the result of an unsecured camera bouncing around and snapping images of
the lake bottom and rotting logs? I can't say for certain, but I lean toward the latter.
