how to remove overlay

Hello, how to remove the overlay on the picture, it looks so dark , the rotating pictures in the home page, thanks
 

Hello,

Edit file /media/templates/site/carwash/css/custom.css and change the value here (around line 108):

Use a decimal value between 0 (total darkness) and 1 (no darkness). For example, use 0.5 or 0.7, etc.

Regards,
Milos

.carouselrow .hot_swipe_carousel_slides img {
    filter: brightness(1.0);
