There are 3 things that we all do on the beach in Hawaii.  We stand, walk and sit.    Simple variations on these three themes make the most natural looking   portraits.  Being creative with posing people is a big part of the value of a   photographer.  Though it happens all too often with the average photographer,    you can’t just “wing it”.  Most people are not professionals in front of the   camera, so the photographer has to know how to make you look good and how to give   you variety to choose from.
      Just shooting a bunch of “candids” can get old   quickly.  You need to organize the shoot to get a mixture of nicely posed portraits   and also include candids.  A professional will not just leave this up to   chance.
