A short video showing what I used to make the bokeh effects which I did with my new years video showing happy 2011 in fireworks. I actually used the P194 or the P375 set which has a filter or gelatine holder for the Cokin P filter holder. Then I cut out a shape that is within 2cm out of a black card board and place it in the gelatine holder and now have a nice filter for bokeh effects. You can also put a piece of clear plastic and use a marker to draw or write something inside the bokeh.
