Oh.. Bokeh...
We could debate all night on how to pronounce the damn word...LOL
As Medley says, you need a large aperture and probably a long focal length to get nice Bokeh... it is the pattern caused by the out of focus objects in your picture... I recommend checking out the DPChallenge site (
www.dpchallenge.com) they have run a number of Bokeh competitions and the top contributors usually write up the methods used to obtain the results...
The other thing about Bokeh is that to get the nicer effects you usually need higher quality glass... I have had best results with a Canon 70-200 F4 L.. set at 200mm and f4 and close focusing on the subject...
You are going to struggle with the DSC H7 as it is not going to be as able as a DSLR. I suggest you try it in macro mode and focus at the extent of your zoom as close to the subject as possible... try with an object such as a Christmas tree with fairly lights in the background to help make the Bokeh more obvious... hope this helps..
