Dear Rob and Jerry,

      The LLRGB technique is truly remarkable in enhancing color 
without appearing to increase noise or lose information.  The 
blurring technique might make for a more pleasing appearance but at 
the price of a loss of true resolution and a raising of background. 
Am I missing something here?
