How can I adjust the zoom on my collection banner image in the NORTH theme?

[earljp01]

Hi

How do i change the collection banner image on the collection page as it is zoomed in. However i dont want to get rid of the collection image on my back end.

I Want to keep this as the image for the home page as the image size is a good fit. 

 However, i dont like this as it is too zoomed in but it is the same image as the top one (COOKING) but i cant seem to change it without it changing every image.

Hope this makes sense.
