Increase opacity of sold out images in brooklyn

Store Design
1

Hello. My sold out images are greyed out in Brooklyn theme. I would like them to be the same as the non sold out images (but keep the ‘sold out’ icon. My second issue is that my sold out items are appearing larger than my non sold out items. I would like them to all be the same size. Any help would be hugely appreciated. Thanks, Luke
