You know the hardest question I get these days is, "What do you specialize in?" I have spent many thousands of dollars of the last 2 decades on my continued education. I love what the camera can do when you know what to do with it! The basic knowledge of exposure, depth of field, color and composition makes my world rock! It's actually the only way I see life these days. I am constantly seeing a shot! I am also constantly aware of what is a good image and what will not be a good image before I even snap the shutter. This is from many years of shooting the wrong way and learning how to see the correct way. Interior images of rooms have always been one of my favorites to photograph.  The way you compose the image is SUCH A BIG DEAL!!!  The lights in the room set the mood and the way you choose to expose your image will give you the depth you are looking for.  For most it's boring stuff but to me everything is a challenge to make it look better than as it is.  This is what I'm trained for.  :)
