Change the opacity on slideshow

Hi,

I would like to remove or reduce the opacity of the slideshow please?

We use a mask over the image slide: /templates/ja_diner/images/mask-slideshow.png

To remove it, you can use this custom CSS:

.acm-slideshow .item .mask {
    background-image: none !important;
}

For this one: http://lcm.re/new/ , you can override with this custom css:

.acm-slideshow .item:before {
    opacity: .7 !important;
}

and change the opacity to the value you want.
