Okay Bokeh Mokey

Bokeh is the word for the pretty blur a good camera can put in the out of focus area behind a subject. Sometimes this mean you just have some really blurry grass. Even when using a film camera, there is bokeh. A good example, next time you're watching a romantic movie and there is a close up of the couple eating dinner in a dimly lit courtyard with some lights behind them, check out the shape of those out of focus lights. Depending on the shape of the aperature diaphragm the out of focus lights will be sculpted into different shapes. By applying a filter, one can manipulate the bokeh so instead of taking the shape of the aperture diaphragm, it takes the shape of the filter. That was a lot of fancy talk that means, put a filter in front of your lens and the out of focus lights can be made into different shapes.

To achieve this effect it is good to have tiny point sources of light. This might be a city skyline or a strand of Christmas lights. So I stripped the tree (which I should take down anyway) and tacked the lights on the wall behind my subject. The first is shot with my 50mm f/1.4. You need a lens that will open really wide (low f stop) and portrait lenses are usually good for this; they are, after all, made for good bokeh like you see in portraits. The second is with a filter. Sound expensive? It cost me nothing. Just take some thick black paper (don't have any? I used an index card and permanent marker) and cut it into the size of your lens, cut a shape in the middle and tape over the lens. These are not the coolest I've ever done but I had some fun creating them. You can find some great bokeh tutorials online and resources about creating filters. There is this great site and it is called.... google. Just google it, bokeh tutorials are all over the place and I'm too lazy to find a good one for you.
