Shannon, the object within the circle is from the high res photo although it has not been enhanced in this picture.
Yes I realize that the encircled image is just a higher resolution version of the original Nessie photo from almost two years ago, but is it enhanced? "Enhanced" is a generic term, and just re-scanning at a higher resolution would "enhance" it to some degree. I assume you meant "enhance" as in running some software magic on it, like edge detection, hi pass filtering, contrast and brightness adjustments, leveling, normalizing, shadowing, etc. etc.
What I meant is that the image posted on CNN per the link above is what I believe I saw in 2010, during Dr. King's presentation, and if contrasted side-by-side with the low resolution Nessie photo, shows remarkable differences in detail.
The low resolution pic looks to my aging eyes as if the tire is the most vertical part of the object, supported by the struts below it, stuck into a crevice. The high resolution pic looks as if
the steel hardware is somewhere near horizontal or slightly diagonal, and entangled in a small mess of wreckage, with the toroidal black tire still inflated and view-able at any number of oblique angles.
A key to these images is the TIGHAR Tracks Oct. 2011 summary of Nessie's analysis, identifying that the "worm" type of landing gear on NR 16020 is consistent to what is identifiable in the photograph's components. The worm gear has the same, if a slightly larger, radius as the fully inflated tire.
