Lightbox question

[torndownunit]

I am playing around with the Highslide variation of Lightbox. I hope I can explain this right, but I am trying to figure out how to adjust how the original page appears when you click a thumb and the lighbox popup opens. EG I notice on a lot of pages when the popup opens, the page behind it 'dims' or goes out of focus so that the popup stands out more.

By default, both the popup and the page behind/under it appear the same right now. It makes it kind of hard to look at.

It looks like there is a dimmingOpacity property that can be set, which I think is for the background opacity. The examples on the Highslide page don't have the dimmed background so it's definitely possible.
