I finally get a chance to try the DIY Bokeh and I'm LOVING IT! Below is my DIY Heart Shaped lens hood. The black paper cost $0.39 from local craft store and lots of tapes. I was able to make 3 of these fake lens hood from it.
This is the result. Not bad huh??? I'm still working on trying to get the foreground/target to focus right. This is the first time I have to use manual focus and as you can see, I'm not very good at MF.
