Maybe not intentionally cruel but we'll do whatever it takes to get the shot.  At times that doesn't end up going well for models.  Take this shoot with model and USC Track and Field athlete Lyndsey Lopez.  That day was already cold and windy here in San Francisco.  Our famous fog was starting to roll in further chilling everyone on location.  She got her frigid workout in that day all with a smile on her face.  Even after I had her to run through the frame again and again and again and again... jumping, stretching, sprinting.  Talk about a true champion.
