I just got this digital camera for Christmas, and I'm still trying to figure a few things out. I'm relatively new to photography, so I'm hoping someone here can help me out. A lot of my pictures come out blurry. I'll be sitting perfectly still and take a picture, and it'll come out as if though my hand was shaking like a crack whore. I've tried different ISO settings, and a lot of pictures end up blurry no matter what. Any idea what could be causing this?
