I’m trying to figure out what effect is used on these thumbnails?

[http://www.karinabednorz.de/](http://www.karinabednorz.de/)

Are there two seperate thumb images used, one at lower brightness and the other at normal, then faded in? Or is it AS and changing the opacity on a darkened image?

Thanks
