One of my favorite, if not my most, photography techniques is called bokeh. Bokeh (pron. bok-uh) comes from the Japanese term for blur. Many photographers use this technique to bring attention to the subject by blurring the rest of the photo. This is done by using a very shallow depth of field (DOP). What this really means is that the camera only focuses on one very thin slice of space and the rest is blurred. I use my Nikon d200 50mm 1.8f prime lens to get this effect. I personally like to use the technique to show beautiful lights and design out of focus. Here is an example: I focused on the Korean sign in hopes of capturing the sun setting on the graffiti to the right. As you can see, the light is more diffused towards the right of the picture because of the distance from my focal area.
