Sizing thumbnails differently in product pages

Site URL: https://www.angelinapilarinos.com/

Hi I'd like to know if there is a way to make one of my product pages have thumbnails that are 3:2 aspect ratio, and then have a different product page with thumbnails that are 2:3 or another aspect ratio.  I am using a Bedford template and at the moment if I change the size of one product pages' thumbnails, all the product page thumbnails change.  Not ideal when I have vertical and horizontal pictures.  Thanks!
