NoVaGator, actually the telephoto lens DOES have something to do with the fuzzy background. A longer lens offers a more limited depth of field allowing the photographer to more easily separate his subject from the background. No doubt that the aperture has the largest effect on the image's depth of field, but the lens type changes things quite a bit.
Once you get passed the point of getting your photographs exposed properly (it took about a year of seriously figuring this out for me to get it right), the one thing that helps me get a lot of wall-hangable photographs is to ask myself a question before I hit the shutter release. While looking through the eyepiece I ask, "Would I want to see this framed in my house?" Oftentimes, the answer is "no." So WHY am I taking the picture? I find that I've upped the number of nice shots on a roll from one to three. Of course, those amazing, WOW shots don't come too often and when they do come, it's because I was at the right place at the right time or because I was trying something incredibly strange and it just happened to work out.
What I find funny about being interested in photography and shooting are the looks I get when I say things like, "I was out shooting some horses this weekend..."
