Are there other selectors like brightness, hue, contrast besides Alpha(opacity=75);/-moz-opacity: 0.75;?

I have yet to find anything other than Alpha.

I have a group of images links that I would like to be full opacity and brighter during the mouse over. Below is what I'm currently using.

HTML Code:
.highlightit img{
filter:progid:DXImageTransform.Microsoft.Alpha(opacity=75);
-moz-opacity: 0.75;
}

.highlightit:hover img{
filter:progid:DXImageTransform.Microsoft.Alpha(opacity=100);
-moz-opacity: 1;
}
Thanks for any help or suggestions,
Robert
