This has been an eternally infernal part of the problem for me (a minor part since I just don't see the same things as some others anyway). Short of having a known object to scale by, I don't see how one can scale these. Tim's 'fuselage' may only be inches long so far as I can tell.
You can't judge scale, Jeff, because you don't have the tools at your disposal that I do. The subject is visible in both High Definition and Standard Definition videos (neither of which is yet available to you for this portion of the July 14, 2012 dive). While neither video has a built in scale, as such, the Standard Definition video does have a calibrated depth meter displayed (in feet and tenths). As the camera moves inexorably downhill, one quickly learns how to judge the change in depth relative to the passing scenery displayed. Since the slope approximates 45
o, then a horizontal movement is essentially the same as a vertical movement, thus giving approximate scale in two dimensions (dividing by 1.414, of course).
In addition, the subject picture was captured from a much larger landscape, which contains other items related to the Electra (
viz. engine components, a propeller blade, both pitot tubes, and possibly part of a wing). All these items seem to scale well against each other. Also, the 2012 High Definition video contains 1929x1080 pixels per frame, which my monitor and software can handle, but that may not be true for everyone.
You learn to live with the tools you have. Maybe next time Ric will demand to have parallel lasers pointing out from the ROV to create a meter-long scale between the two red dots cast onto the landscape.
