Here is another example of bokeh, this time the goal was to bring the focus into the bottom 1/3 of the frame, sandwiching it between two areas of blur.
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.
Here’s shot number 3 from my Insa-dong journey. This is a man putting the final touches on some Korean 한과 (snack) called 감정 (Gamjung). It is very sticky but quite tasty. Insa-dong has a lot of stalls selling all types of snacks, some sweet, some not so (boiled larvae). I personally try to steer clear of the putrid smelling larvae and go with gamjung.
