In low contrast and high brightness with TriX  I would take a red filter 
and place the sand on about a zone IV and develop at N+2.  Anything with 
darker tones will drop to Zone II or I and anything green will drop 
out.  If there is nearby foliage where you want to keep detail then place 
the foliage on a zone about III and develop normal or N-1.
