Christmas Through the Keyhole
Experiments December 2012, Mountain City, TX
One is probably used to seeing photographs that fade to a border.
That can be easily accomplished in digital software, but before digital processing the effect used to be accomplished by special masks either on the camera or during processing. I decided to play with this a bit and see if I could create a lens mask that might approximate what a person (child?) looking through a keyhole in a door might see.A Bokeh mask can be used to give different shapes to defocused lights. But if brought into focus, it will create a border around a reduced area. I made my mask out of construction paper (see below figures for the basic construction concept). The mask is attached to the lens using a rubber band.
Some Bokeh photography uses special lenses instead of masks. Mine took about 5 minutes to fabricate and use; however it is not as specialized as those many professional photographers use. To see more information regarding Bokeh techniques in photography click here.
