Yes, true, and, as such, tells us so much more about the beings making the photograph than it does about the object being photographed. As for using scalecubes as a basis for measuration, you can utilize an existing arsenal of projective geometric calculation in a pinch. But, if what you wanted from the start was measurement, you would photograph everything by placing it inside a half cube -- floor, back, and side -- that was white and gridded off in your choice of units (centimeters, inches, or the 60th part of a Babylonian cubit), and shooting it at different orientations (6). It would then be medium easy to use a computer algorithm that would convert the images to measurements or a 3D model in a few teraflops. This is what should be done with meteorites (and "Moon Rocks," and pieces of UFO's if you got'em). Then, instead of pictures of the Meteorite of the Day, we would have the virtual object of the Meteorite of the Day. It wouldn't be scientifically useless to be doing that with important pieces even today. Maybe, scalecubes are just more Fun? Cooler? Sterling K.

Another hobby I have is making replicas of props from various science fiction movies I have used photos to reverse engineer parts and have done so with amazing accuracy A perfect example is an MG-81 Flash Hider/ Booster that was use on Han Solo's "Blaster" from Star Wars. This part went unidentified for 26 years but I and a small group of hobbyists created and manufactured replica of this part from the various available photos. About 3 years ago, it was finally identified and a mint specimen was found and borrowed, they have a value of about $3000 so we were lucky the guy let use it. To even my own surprise my Flash Hider was surprisingly accurate to the real thing. Here is a picture, the real prop is on top and my replica is on the bottom http://i131.photobucket.com/albums/p298/BobaDebt/Flashhiders.jpg Bear in mind that this is just one image of a single prop, they used a variety of props and each had variances in the parts. For instance in the above picture the holes are look smaller but there are other pictures that they look bigger. However, when I compared my replica to a real MG-81 Flash Hider most of my measurements were off by less then .005" of an inch which is pretty good. --------------------------------------------------------------------------------- Hi, All Measurement from a photo with a scalecube in it is impossible except in the case of a very elaborate photo setup designed to make such measurements possible and even then, the precision is low. aying Sterling K.
