I believe you want macro on, and take pics in natural light to start with so you can have the flash off. Don''t zoom in too close, the diamond shouldn''t be taking up even close to the whole frame!! Most people just crop & zoom using photoshop after.
so thats what that flower means....LOL... so whats the mountain then?? Just the outside mode? I have had my camera for almost a year and I still have no idea how most of the stuff works on it..
