A great photograph can invoke feelings and stir the emotions in a way that few other things can. To produce such a photograph takes planning and time. So many people see a great scene, whip out their camera and take the shot. Later when they are home reviewing that picture they realize it didn't not capture any of the inspiration they felt.
They first key to capturing a great photo is taking your time to setup the scene. Try to get it from a perspective that is not head height. Step way from the scenic view area and look for a new place to take the photo from. Also don't forget to use your LCD to review the photo before you walk away.
Once you have a technically sound photo it must them be process and adjusted to really become what you saw in person. My photography really started to shine once I finally found my grove post processing. I shoot all of my photos in raw format. Below is example of what I get out of the camera and what it looks like after 15 to 20 minutes of post processing work.
You can see the before picture on the left is very dull and has no life. It is the same photo but the life is just not there. The photo on the right is what the scene looked like in real life. Post process can certainly be over done, but it is essential to making a great photo.
