How to change slider photo hight?

I can't figure out where to change the width and hight of the slider option whick seem to be 950x350px. However, I want to change the hight to 450px. I would much appreciate your help. Otherwise it's a great and easy theme!

 

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

#slides .slide {
    height:450px;
}
 
#slides .slide img {
    height:450px;
}
#slides .slide iframe {
    height:450px;
}

 

Many thanks for the code! It worked very well!
