Selectors with $(this)

Selectors with $(this)

Hi, I try to use a hover on a page with thumbnails
When I roll over a thumbnail, I want to change the color of the caption..

$('.drop-shadow').hover(function() {
      // this is what i want but only for the hovered image
      // $('.drop-shadow p').css({ color: "red" });
      
      // try..
      // $(this > "p").css({ color: "red" });
      // $(this p).css({ color: "red" });
      // $(this "p:last-child").css({ color: "red" });

      // do i need to wrap 'this' in a jQuery object?
      // var $this = $(this);
      // how??
   
         }, function() {
      // back to normal text color           
         });
