Blurry Picture on Collection page - Brooklyn Theme

I have problem with the uploaded picture`s quality for my products. I have read a lot about, and nobody seems to have a solution here. Is it possible to make something with it or do I have to choose a different theme? I would like to sell jewelry and I need nice pics.

On the collection page all the products look blurry, like this.

On the product page, if I click on the product (same pic), it looks ok.

Is it a filter or something on the collection page? I have taken down the picture background color to none…but I cannot find any other option to improve it.

I really like this theme and would like to keep it.

All response are appreciated.
