Scroll and zoom images

Site URL: https://www.favillastudio.dk/workshops

Can anyone help. I love this site - https://www.favillastudio.dk/workshops and I really want to get my images to do the same with the scrolling and zoom fuction when you scroll down the page. I know theres the reveal animation option but I want it to be stronger like the favilla site and also to have the zoom function once its been revealed.

Any help would be welcome 🙂
