There is nothing magic about photogrammetry although it appears so to the 
layperson.  This package cannot pull color and cannot pull texture from the
photos.  This package cannot apply such to any model.  The package is a
simple photo-triangulation application.  The package is not capable of giving
accuracy estimators for computed points in XYZ object space.  This package is
suitable for non-critical applications where the magnitude of inherent errors
are not important.  If you do not care what your errors are, if the end results
are OK if they "look OK", then this may be the package for you.

If, on the other hand, 'ya gotta be sure everything REALLY is OK; 'ya gotta 
have proof ...'  Better send me an e-mail message for the real stuff.
