I saw this image in the new products today. This is the only image in the product content that has this filter or shader used on it.

I love the style. Can anyone point me to the product (shader/filter) used to create this look? Thanks.

Topaz Studio has some very cool filters. There is a free trial to check if it has the tools and look  you need.

The colours just look desaturated to me.
