Until this challenge, I never heard of "bokeh." As a seat of the pants photographer, I have not taken the time to really study. It's the story of my life, not reading the directions for my cameras and computer. So, I looked back through some of my gazillion photos and picked out some that were examples. Now I have to figure out how to do it on purpose.
From Wiki: “Bokeh occurs for parts of the scene that lie outside the depth of field. Bokeh is often most visible around small background highlights, such as specular reflections and light sources, which is why it is often associated with such areas. However, bokeh is not limited to highlights; blur occurs in all out-of-focus regions of the image.” Bokeh is not just for DSLRs with fast lenses. While bokeh is easiest to create with a DSLR due to their larger sensors, it is not impossible to do with a point & shoot.
Bokeh is created in one of two ways. A short focal length between the camera and the subject and wide aperture (small number, i.e. f/2.8 if your lens will open that wide) while keeping the background as far away as possible. A long focal length between the camera and subject, and the widest corresponding focal length while still keeping the distance between the subject and background as large as possible. A longer focal length will increase the depth of field – a larger focus plain – so the background would have to be farther away than with short focal lengths, otherwise it will all be in focus!
